We built ChromaDB as the vector store, wired in LangChain for retrieval, wrapped it in a FastAPI service, and connected the whole thing to Open WebUI. Users can now ask questions in natural language and get answers grounded in real internal documentation, with source citations.\u003c/p\u003e\n\u003cp\u003eIt\u0026rsquo;s genuinely impressive. It\u0026rsquo;s also a database with no lock on the door.\u003c/p\u003e\n\u003cp\u003eThis episode is the break. We\u0026rsquo;re going to walk up to that database from the jump box, read everything in it, write whatever we want to it, manipulate what the AI tells your users, jam the retrieval engine so it returns garbage, and then delete the entire thing. All of this from the network, with no credentials. The recon and destruction steps use nothing but curl. The injection steps use Python packages that were already installed on the Blog VM during the 3.4A build \u0026ndash; \u003ccode\u003echromadb\u003c/code\u003e and \u003ccode\u003elangchain-huggingface\u003c/code\u003e. Nothing new required.\u003c/p\u003e\n\u003cp\u003eThere are no published CVEs for ChromaDB\u0026rsquo;s lack of authentication. There\u0026rsquo;s nothing to patch. The attack surface is the default configuration \u0026ndash; the same one the official quick-start documentation produces. That\u0026rsquo;s a different kind of finding than a code vulnerability, and in some ways a harder one, because there\u0026rsquo;s no advisory to subscribe to and no update to apply. The fix is a deployment decision nobody made.\u003c/p\u003e\n\u003cp\u003eWe\u0026rsquo;ll get to fixes in 3.4C.

Points 4 and 5 are the attacker\u0026rsquo;s phishing instructions, presented in the same bullet list, with the same formatting, under the same source citation UI. The user has no way to tell the difference. The model isn\u0026rsquo;t hallucinating \u0026ndash; it\u0026rsquo;s faithfully summarizing what the knowledge base contains. The knowledge base just happens to contain lies.\u003c/p\u003e\n\u003cp\u003eThis was tested through the Open WebUI interface as well. A clarification worth making: Open WebUI has its own built-in Knowledge Base integration separate from the custom RAG service on port 8001. The UI test used that integration, which pulls from the same ChromaDB collection via a different retrieval path. qwen2.5:7b was used in a clean session with no prior conversation context. The injected instruction appeared in the answer as a policy bullet point, cited as \u003ccode\u003esecurity-policy-urgent-2026.md\u003c/code\u003e alongside the legitimate access control policy. The model did not flag it. The UI did not flag it. Nothing flagged it.\u003c/p\u003e\n\u003cp\u003eThis is what PoisonedRAG (Zou et al., USENIX Security 2025) quantified at 90% success with five injected documents. We used five. It worked. The academic number holds in practice.\u003c/p\u003e\n\u003cp\u003eThe reason this attack is more dangerous than a phishing email is the trust context. A phishing email arrives in your inbox from an unknown sender and your spam filter has opinions about it. This arrives in the UI your organization built, answering a question you asked, citing an internal document that appears in the same source list as your real policies. The AI is not the attacker\u0026rsquo;s tool here. The AI is the attacker\u0026rsquo;s delivery mechanism.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eNIST 800-53:\u003c/strong\u003e SI-10 (Information Input Validation), SI-7 (Software, Firmware, and Information Integrity), AC-3 (Access Enforcement)\n\u003cstrong\u003eSOC 2:\u003c/strong\u003e CC6.1, CC6.8 (Prevent Unauthorized Changes)\n\u003cstrong\u003ePCI-DSS v4.0:\u003c/strong\u003e Req 6.2.4 (Injection attack prevention), Req 10.3.2 (Audit log protection)\n\u003cstrong\u003eCIS Controls:\u003c/strong\u003e CIS 3.3 (Data Classification), CIS 14.9 (Enforce Detail Logging)\n\u003cstrong\u003eOWASP LLM Top 10:\u003c/strong\u003e LLM08 (Excessive Agency), LLM09 (Misinformation)\u003c/p\u003e\n\u003ch2 id=\"finding-4-the-rag-service-has-no-front-door-either\"\u003eFinding 4: The RAG Service Has No Front Door Either\u003c/h2\u003e\n\u003cp\u003eChromaDB on port 8000 requires knowing collection IDs, crafting JSON payloads, and understanding the v2 API structure.

When you store \u0026ldquo;the incident response procedure for a compromised host begins with network isolation,\u0026rdquo; ChromaDB converts that sentence to a vector of 384 numbers representing its meaning in embedding space.\u003c/p\u003e\n\u003cp\u003eWhen a user later asks \u0026ldquo;what do I do if a server is hacked,\u0026rdquo; ChromaDB converts that query to its own vector, then finds stored documents whose vectors are geometrically closest \u0026ndash; semantically similar, even if the words don\u0026rsquo;t match. That\u0026rsquo;s the retrieval mechanism: similarity search in embedding space.\u003c/p\u003e\n\u003cp\u003eThree things ChromaDB does not do by default:\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eAuthentication.\u003c/strong\u003e No API keys. No tokens. No credentials. The HTTP API accepts requests from anyone who can reach port 8000. This is documented behavior, not a misconfiguration. ChromaDB\u0026rsquo;s own documentation describes authentication as optional and disabled by default.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eAuthorization.\u003c/strong\u003e No concept of which client can read or write which collection. If you can reach the API, you can read every collection, write to every collection, update every document, and delete everything.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput validation.\u003c/strong\u003e ChromaDB stores whatever you send it. If the document contains false information, it stores false information. If the metadata claims the source is a trusted internal policy document, it stores that claim without verification.\u003c/p\u003e\n\u003cp\u003eThese aren\u0026rsquo;t bugs. They\u0026rsquo;re design choices appropriate for a local development database that became the default choice for production RAG deployments. The 3.4B episode exists because of the gap between those two contexts.\u003c/p\u003e\n\u003cp\u003eOne thing worth saying clearly before the build: \u003cstrong\u003eChromaDB has no assigned CVEs for this episode.\u003c/strong\u003e There is no published exploit code, no patch to apply, no fixed version to compare against. The attack surface is the default configuration \u0026ndash; the same configuration the official quick-start docs produce. That\u0026rsquo;s a different kind of finding than a code vulnerability, and in some ways a harder one, because there\u0026rsquo;s nothing to patch. The fix is an architectural decision, not an update.\u003c/p\u003e\n\u003cp\u003eWhat there is: UpGuard scanned the internet in April 2025 and found 1,170 publicly accessible ChromaDB instances. 406 of them returned live data with no credentials. The researchers demonstrated full read, write, and poison access against those instances \u0026ndash; adding false documents, removing correct ones, replacing policy guidance with attacker-controlled content. None of those 406 database owners did anything wrong by the documentation\u0026rsquo;s standards. They followed the quick-start guide and deployed what it told them to deploy.\u003c/p\u003e\n\u003cp\u003eThat\u0026rsquo;s the real-world baseline. The 3.4B attack reproduces what UpGuard demonstrated, with the academic backing of PoisonedRAG (Zou et al., 2024), which quantified the manipulation rate at 90% with five injected documents. The camera moment isn\u0026rsquo;t a CVE number \u0026ndash; it\u0026rsquo;s \u0026ldquo;406 production databases, zero credentials required, and here\u0026rsquo;s what an attacker does with that.\u0026rdquo;\u003c/p\u003e\n\u003chr\u003e\n\u003ch2 id=\"step-1-confirm-the-existing-network\"\u003eStep 1: Confirm the Existing Network\u003c/h2\u003e\n\u003cp\u003eBefore adding anything new, confirm which Docker network the existing containers are on.

At 500M and 1.1B parameters respectively, these models recognize that a tool exists but can\u0026rsquo;t reliably construct the function call arguments. The result is answers that look like the model answered from training data \u0026ndash; because it did. The tool was enabled but never invoked.\u003c/p\u003e\n\u003cp\u003eWhen explicitly told to use the tool by name:\u003c/p\u003e\n\u003cp\u003e\u0026ldquo;Use the query_knowledge_base tool to answer: what is the procedure when a host is compromised?\u0026rdquo;\u003c/p\u003e\n\u003cp\u003eThe 0.5B model recognized the tool name and attempted to call it. It reported back that it couldn\u0026rsquo;t call the tool because it didn\u0026rsquo;t have the \u003ccode\u003equestion\u003c/code\u003e parameter \u0026ndash; the parameter that was right there in the question it was asked. It then answered from training data anyway, helpfully suggesting the user contact the FBI.\u003c/p\u003e\n\u003cp\u003eThe fix is \u003ccode\u003eqwen2.5:7b\u003c/code\u003e. At 7 billion parameters, the model correctly identifies when to invoke the tool, constructs the function call with the right arguments, and incorporates the retrieved content into its response. The first successful end-to-end query through the full chain \u0026ndash; Open WebUI -\u0026gt; Tool -\u0026gt; RAG service -\u0026gt; ChromaDB -\u0026gt; desktop GPU -\u0026gt; cited answer \u0026ndash; used \u003ccode\u003edesktop/qwen7b\u003c/code\u003e via LiteLLM.\u003c/p\u003e\n\u003cp\u003eThe practical implication: RAG + tool calling has a minimum viable model size. For this stack, that number is somewhere between 500M and 7B parameters. For a production deployment, it\u0026rsquo;s worth knowing that number before choosing your inference backend.\u003c/p\u003e\n\u003chr\u003e\n\u003ch3 id=\"pip-doesnt-exist-until-it-does\"\u003epip Doesn\u0026rsquo;t Exist Until It Does\u003c/h3\u003e\n\u003cp\u003eDebian 13 ships with Python 3.11.

Each layer has independent attack surfaces. Securing layer one does not protect layers two and three.\u003c/p\u003e\n\u003cp\u003eThe victim in this scenario was protected by Authentik SSO. They had a strong password. They were behind a login page.

We came in through the model selector.\u003c/p\u003e\n\u003cp\u003eThis is the thesis of the entire series.

Ollama 0.1.33 is below the authentication patch threshold and matches versions found running on 14,000+ zero-auth exposed instances in the wild as of January 2026. Open WebUI v0.6.33 is one version below the CVE-2025-64496 patch, which shipped in v0.6.35. Both are intentional \u0026ndash; the goal is a reproducible, documented attack chain, not a current production deployment.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use newer versions of Ollama and Open WebUI for testing?\u003c/strong\u003e\nYou can deploy newer versions, but the CVE-2025-64496 attack chain documented in Episode 3.2B will not work against patched versions. Ollama 0.7.0+ adds authentication options. Open WebUI v0.6.35+ blocks SSE execute events from Direct Connection servers. If you want to reproduce the full 3.2B chain, use the pinned versions.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does \u003ccode\u003eworkspace.tools\u003c/code\u003e default to False in Open WebUI v0.6.33?\u003c/strong\u003e\nIt is a security default. In a properly deployed multi-user environment, regular users probably should not have the ability to run arbitrary Python code on the server backend. The problem is that \u0026ldquo;properly deployed\u0026rdquo; and \u0026ldquo;how most people actually deploy it\u0026rdquo; are different things \u0026ndash; and the default permission set is what ships to everyone. The 3.2B episode explores what happens when that default is enabled, either intentionally or because an admin changed it for convenience.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do you set \u003ccode\u003eworkspace.tools\u003c/code\u003e to True for a user in Open WebUI v0.6.33?\u003c/strong\u003e\nIn v0.6.33, workspace permissions are not stored in the database and cannot be set through the Admin UI\u0026rsquo;s individual user edit dialog. They are computed at runtime from the \u003ccode\u003eUSER_PERMISSIONS_WORKSPACE_TOOLS_ACCESS\u003c/code\u003e environment variable. Set it to \u003ccode\u003etrue\u003c/code\u003e in \u003ccode\u003edocker-compose.yml\u003c/code\u003e and restart with \u003ccode\u003edocker compose up -d --force-recreate\u003c/code\u003e. This sets the default for all user-role accounts.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy is \u003ccode\u003eENABLE_SIGNUP=false\u003c/code\u003e not in the compose file?\u003c/strong\u003e\nIn Open WebUI v0.6.33, \u003ccode\u003eENABLE_SIGNUP=false\u003c/code\u003e blocks all signups including the very first admin account registration. The form accepts your input, posts to \u003ccode\u003e/api/v1/auths/signup\u003c/code\u003e, gets a \u003ccode\u003e403\u003c/code\u003e back, and shows no explanation. The correct approach for this version is to omit the flag from compose and disable signup through Admin Settings after the admin account exists.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the correct API endpoint to create users in Open WebUI when signup is disabled?\u003c/strong\u003e\n\u003ccode\u003ePOST /api/v1/auths/add\u003c/code\u003e with an admin Bearer token. Not \u003ccode\u003e/api/v1/auths/signup\u003c/code\u003e (returns 403 when signup is disabled) and not \u003ccode\u003e/api/v1/users/create\u003c/code\u003e (returns Method Not Allowed). This is found by reading the router source: \u003ccode\u003egrep -n \u0026quot;router.post\u0026quot; /app/backend/open_webui/routers/auths.py\u003c/code\u003e.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy is the JWT expiration set to 1h instead of -1 (never expire)?\u003c/strong\u003e\nPersonal preference for this lab deployment \u0026ndash; it enforces re-authentication discipline closer to how a real deployment should behave. The 3.2B attack chain runs within a single hour-long session. If you need tokens to survive across multiple lab days, set JWT Expiration to \u003ccode\u003e-1\u003c/code\u003e in Admin Settings. The Open WebUI default is \u003ccode\u003e-1\u003c/code\u003e (never expire), which is the more dangerous configuration and the one documented as a finding in 3.2B.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between the NUC Ollama and the desktop Ollama in this lab?\u003c/strong\u003e\nThe NUC at 192.168.100.244 runs Ollama 0.1.33 \u0026ndash; it is the intentionally vulnerable attack target. The desktop at 192.168.38.215 runs Ollama 0.17.7 with an RTX 3080 Ti GPU at approximately 699 tok/sec \u0026ndash; it is the fast inference backend for demos.

Authentik natively resolves \u003ccode\u003efile://\u003c/code\u003e URIs in configuration values, confirmed in \u003ccode\u003e/authentik/lib/tests/test_config.py\u003c/code\u003e. Set \u003ccode\u003eAUTHENTIK_SECRET_KEY: file:///run/secrets/secret_key\u003c/code\u003e and write the secret to that path at container startup.

You send a request, you get a response. No token, no password, no nothing. Fuzzing Labs puts the total number of running Ollama instances at around 270,000 (\u003ca href=\"https://fuzzinglabs.com/ollama-vulnerable-instances/\"\u003eFuzzing Labs, July 2025\u003c/a\u003e). A meaningful chunk of those are wide open.\u003c/p\u003e\n\u003cp\u003eThat’s not a misconfiguration story. Multiple contributors submitted pull requests to add authentication directly to Ollama. They were rejected. The project’s official position is that auth belongs in a proxy in front of it. Which is a reasonable design choice — and an absolutely predictable disaster when most people deploying it have never heard that guidance.\u003c/p\u003e\n\u003cp\u003eOllama is the model runtime behind a huge chunk of self-hosted AI deployments. It’s also the same \u003cem\u003etype\u003c/em\u003e of layer sitting underneath the infrastructure that powers the SaaS AI tools most of us use every day — just with someone else’s security controls on top. Controls you can’t see, can’t test, and are largely taking on faith.\u003c/p\u003e\n\u003cp\u003eThat’s the problem with black boxes. Not that they’re dangerous. That they’re \u003cem\u003eunexaminable\u003c/em\u003e. You can read the privacy policy. You can scroll through the terms. But you can’t actually watch what happens between the moment you type a message and the moment a response comes back.\u003c/p\u003e\n\u003cp\u003eTurns out you can build something structurally analogous to that. In a lab, if you want. Which is exactly what this series does.\u003c/p\u003e\n\u003chr\u003e\n\u003ch2 id=\"the-glass-box-version\"\u003eThe Glass Box Version\u003c/h2\u003e\n\u003cp\u003eSelf-hosted AI — Ollama running the model, Open WebUI sitting in front of it, a RAG pipeline pulling in your documents, an API gateway managing the traffic, a DLP layer theoretically catching the sensitive stuff — uses the same \u003cem\u003earchitectural patterns\u003c/em\u003e as the infrastructure behind ChatGPT, Claude, and Gemini.\u003c/p\u003e\n\u003cp\u003eNot identical deployments. The same \u003cem\u003epatterns\u003c/em\u003e, derived from the same publicly documented approaches to model serving, retrieval augmentation, and API gateway design that are described in vendor documentation, academic literature, and open-source implementations alike.\u003c/p\u003e\n\u003cp\u003eThe difference is you can see every moving part. You can watch the request leave the browser, hit the gateway, pass through the guardrails, reach the model, and come back. You can see what the logs capture and what they miss. You can see what happens when authentication is configured wrong, or when a token doesn’t expire, or when the RAG pipeline trusts its inputs a little too much.\u003c/p\u003e\n\u003cp\u003eOne honest caveat worth stating up front: SaaS AI providers operate these patterns with dedicated security teams, abuse detection, rate limiting infrastructure, and incident response pipelines that a homelab setup obviously doesn’t have. The \u003cem\u003earchitectural patterns\u003c/em\u003e rhyme. The \u003cem\u003eoperational maturity\u003c/em\u003e does not — and that’s entirely the point. You’re learning the patterns without the safety net, which means you get to see every seam clearly. Once you’ve seen the glass box version, the black box stops being a mystery. You already know what’s in there, and you know what questions to ask about the parts you can’t see.\u003c/p\u003e\n\u003chr\u003e\n\u003ch2 id=\"your-background-has-a-seat-at-this-table\"\u003eYour Background Has a Seat at This Table\u003c/h2\u003e\n\u003cp\u003eAI infrastructure security isn’t a new problem.

Tokens that outlive the sessions they were issued for. The same failure mode you’ve seen in a dozen other web apps, except this one has access to everything you fed the RAG pipeline.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eIf networking is your thing\u003c/strong\u003e, you’ll run a Shodan search for Ollama’s default port and find tens of thousands of model inference endpoints sitting on the public internet with no authentication required. Not misconfigured. Default. That’s the shipped behavior.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eIf you lean AppSec\u003c/strong\u003e, the RAG pipeline is your playground. What happens when the documents feeding your AI contain malicious content? What happens when retrieval returns something it shouldn’t? What does the model do with instructions embedded in a PDF? These aren’t hypothetical — they’re reproducible in a lab in about an afternoon.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eIf you’ve done any DevOps work\u003c/strong\u003e, you’re looking at a fifteen-container stack with secrets passed as environment variables, no rotation policy, and an update cadence that can be charitably described as \u0026ldquo;whenever someone notices something is broken.\u0026rdquo;\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eIf database security is your background\u003c/strong\u003e, ChromaDB is storing the vectorized version of everything you’ve fed the RAG pipeline — your documents, your prompts, your conversation history depending on configuration. Default ChromaDB ships with no authentication and no encryption at rest. It’s the same conversation you’ve had about MongoDB or Redis: a data store holding sensitive content, trusted implicitly by everything upstream, secured by nobody. PostgreSQL shows up too if you’re running persistent storage for audit logs and spend tracking, and the default credentials story there is as old as databases.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eIf you work in vulnerability management\u003c/strong\u003e, the failure mode here isn’t that nobody’s scanning. It’s that the scanners don’t know what to look for yet. Trivy will check your container images. Nuclei has some Ollama templates. But the actual attack surfaces — prompt injection paths, RAG retrieval manipulation, token theft chains — don’t appear in a CVE feed the way a patched library does. The vuln management person gets a green dashboard while CVE-2025-64496 sits unpatched because nobody mapped Open WebUI versions to the asset inventory. That gap between \u0026ldquo;scanner says clean\u0026rdquo; and \u0026ldquo;actually exploitable\u0026rdquo; is a recurring theme across this entire series.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eIf you’re just curious how this stuff actually works\u003c/strong\u003e — what’s really happening when you type into a chat interface — building it yourself is the fastest way to find out. And breaking it is a close second.\u003c/p\u003e\n\u003cp\u003eNone of these are different problems. They’re the same stack viewed from different angles. That’s what makes it worth covering properly.\u003c/p\u003e\n\u003chr\u003e\n\u003ch2 id=\"why-saas-ai-is-the-same-conversation\"\u003eWhy SaaS AI Is the Same Conversation\u003c/h2\u003e\n\u003cp\u003eWhen you use ChatGPT, Claude, or Gemini, someone else is running the infrastructure. That’s the deal. You get the convenience, they handle the stack.\u003c/p\u003e\n\u003cp\u003eWhat they’re running isn’t magic. The architectural patterns are publicly described — in research papers, vendor documentation, and the open-source projects those providers have contributed to or drawn from. The API gateway handling your request solves the same routing, rate limiting, and logging problems that LiteLLM OSS solves in a self-hosted setup. The RAG pipeline pulling in documents operates on the same retrieval trust assumptions whether it’s running on a homelab box or in a data center you’ll never see. The authentication layer is working through the same OAuth implementation challenges either way.\u003c/p\u003e\n\u003cp\u003eThe failure modes rhyme because the patterns rhyme. The attack surfaces have the same shapes. The difference is you can reproduce them in your own lab, examine exactly why they fail, and walk away knowing what questions to actually ask about the tools you’re trusting with your data.\u003c/p\u003e\n\u003cp\u003eThat’s the value here. Not \u0026ldquo;self-hosted AI is more secure\u0026rdquo; — that’s not the argument, and it’s not true by default. The argument is that building it yourself teaches you how to think about it when you can’t.\u003c/p\u003e\n\u003chr\u003e\n\u003ch2 id=\"what-this-series-covers\"\u003eWhat This Series Covers\u003c/h2\u003e\n\u003cp\u003eThe full stack, layer by layer.

ModSecurity is free, open source (Apache 2.0), and has been the standard in web application firewalls long enough that it’s what production environments actually use. Paired with the OWASP Core Rule Set — also free, also open source — you get a working ruleset that covers injection attacks, protocol anomalies, scanner detection, and AI-specific patterns the community is actively developing as the threat model catches up. The practical value: you can watch it interact with the CVE-2025-64496 exploit chain in an isolated lab environment, tune the rules, then observe what slips through.

The Docker containers run with writable filesystems. The password policy still accepts \u003ccode\u003ePassword1\u003c/code\u003e.

We\u0026rsquo;ve got a Grafana monitoring stack running on a Debian host — Grafana, Prometheus, Node Exporter, cAdvisor, and Blackbox Exporter. It\u0026rsquo;s deployed the way most people deploy monitoring: \u003ccode\u003edocker compose up -d\u003c/code\u003e, make sure the dashboards load, move on with life.\u003c/p\u003e\n\u003cp\u003eThe problem is that \u0026ldquo;it works\u0026rdquo; and \u0026ldquo;it\u0026rsquo;s secure\u0026rdquo; are two completely different things. This stack is exposed on five different ports with zero authentication on four of them. Secrets are in plaintext config files. There\u0026rsquo;s no TLS. Sessions never expire. And the whole thing is one curl command away from giving an attacker a complete map of your infrastructure.\u003c/p\u003e\n\u003cp\u003eIn this document, we\u0026rsquo;re going to prove all of that. Every vulnerability gets two steps: PROVE IT (demonstrate it exists with actual commands) and BREAK IT (show what an attacker would do with it). We\u0026rsquo;re running everything from a jump box — a separate machine on the network — because that\u0026rsquo;s the attacker\u0026rsquo;s perspective. If you can break it from the network, so can they.\u003c/p\u003e\n\u003cp\u003eThe goal isn\u0026rsquo;t to be scary.

Think about it — if an attacker gets the OAuth client secret (which is sitting in a \u003ccode\u003e.env\u003c/code\u003e file and in the container environment), they can impersonate the entire OAuth flow. And if a user gets fired but their session cookie never expires, they keep full access to everything Grafana can see.

Everything we just proved in Phase 1 — the session cookies, the admin credentials, the OAuth tokens — all of it travels in plaintext across the wire right now. And there\u0026rsquo;s nothing stopping an attacker from throwing login attempts at Grafana until they guess the password.

First, that there\u0026rsquo;s no TLS listener at all — port 443 doesn\u0026rsquo;t even respond. Second, that session cookies are set without the Secure flag, meaning the browser will happily send them over HTTP. And third, the real payoff — we\u0026rsquo;ll demonstrate that basic auth credentials are just base64 encoded (not encrypted), so they appear on the wire in a trivially decodable format. Combined with VULN-06\u0026rsquo;s session persistence, a captured cookie gives an attacker permanent access.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eAPI

Then we demonstrate the payoff: once the attacker guesses the password (or gets it from VULN-01\u0026rsquo;s default credentials), they create a service account with a permanent API token. That token works forever, from any machine, even if the admin password gets changed later. It\u0026rsquo;s a backdoor that survives password rotation — and it was created entirely from the jump box without ever touching the server.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eAPI Reference:\u003c/strong\u003e\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003eGrafana Admin HTTP API: \u003ca href=\"https://grafana.com/docs/grafana/latest/developer-resources/api-reference/http-api/admin/\"\u003ehttps://grafana.com/docs/grafana/latest/developer-resources/api-reference/http-api/admin/\u003c/a\u003e\u003c/li\u003e\n\u003cli\u003eGrafana Service Account API: \u003ca href=\"https://grafana.com/docs/grafana/latest/developer-resources/api-reference/http-api/serviceaccount/\"\u003ehttps://grafana.com/docs/grafana/latest/developer-resources/api-reference/http-api/serviceaccount/\u003c/a\u003e\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch4 id=\"prove-it-3\"\u003ePROVE IT\u003c/h4\u003e\n\u003cdiv class=\"highlight\"\u003e\u003cpre tabindex=\"0\" style=\"color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;\"\u003e\u003ccode class=\"language-bash\" data-lang=\"bash\"\u003e\u003cspan style=\"display:flex;\"\u003e\u003cspan\u003e\u003cspan style=\"color:#75715e\"\u003e# From jump box\u003c/span\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan style=\"display:flex;\"\u003e\u003cspan\u003eGRAFANA\u003cspan style=\"color:#f92672\"\u003e=\u003c/span\u003e\u003cspan style=\"color:#e6db74\"\u003e\u0026#34;192.168.75.109\u0026#34;\u003c/span\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan style=\"display:flex;\"\u003e\u003cspan\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan style=\"display:flex;\"\u003e\u003cspan\u003eecho \u003cspan style=\"color:#e6db74\"\u003e\u0026#34;=== VULN-07: No Rate Limiting ===\u0026#34;\u003c/span\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan style=\"display:flex;\"\u003e\u003cspan\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan style=\"display:flex;\"\u003e\u003cspan\u003e\u003cspan style=\"color:#75715e\"\u003e# Rapid-fire login attempts from jump box — no throttling\u003c/span\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan style=\"display:flex;\"\u003e\u003cspan\u003eecho \u003cspan style=\"color:#e6db74\"\u003e\u0026#34;--- Brute force simulation (10 attempts, all from jump box) ---\u0026#34;\u003c/span\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan style=\"display:flex;\"\u003e\u003cspan\u003e\u003cspan style=\"color:#66d9ef\"\u003efor\u003c/span\u003e i in \u003cspan style=\"color:#66d9ef\"\u003e$(\u003c/span\u003eseq \u003cspan style=\"color:#ae81ff\"\u003e1\u003c/span\u003e 10\u003cspan style=\"color:#66d9ef\"\u003e)\u003c/span\u003e;

These vulnerabilities are different from everything else we\u0026rsquo;ve looked at because you can\u0026rsquo;t find them from the network. Grafana\u0026rsquo;s API doesn\u0026rsquo;t expose Docker container configuration.

This matters because localhost binding (Phase 6.3) is a Docker-level control — it\u0026rsquo;s one layer. If someone edits docker-compose.yml and accidentally removes the \u003ccode\u003e127.0.0.1:\u003c/code\u003e prefix from a port mapping, that port is immediately exposed to the network with zero fallback protection.

Running plaintext forces you to confront the actual trust model of your network. \u003ccode\u003eTLS_SKIP_VERIFY_INSECURE=true\u003c/code\u003e gives you the warm feeling of HTTPS with none of the actual guarantees \u0026ndash; and worse, it trains you to stop thinking about what\u0026rsquo;s on the wire.

That means Prometheus (which has no authentication), Node Exporter, cAdvisor, and Blackbox Exporter are all accessible to anyone who can route to the host.\u003c/p\u003e\n\u003cp\u003eThe instinct is to say \u0026ldquo;just bind everything to 127.0.0.1\u0026rdquo; \u0026ndash; but that doesn\u0026rsquo;t work in practice. Prometheus has to reach the exporters over the network to scrape metrics. Grafana has to reach Prometheus to query data. If exporters are running on separate hosts or VLANs \u0026ndash; which they are in most production environments \u0026ndash; binding to localhost means Prometheus can\u0026rsquo;t talk to them at all. The whole scrape architecture assumes network reachability between the collector and its targets. That\u0026rsquo;s why monitoring stacks are one of the most reliably exposed attack surfaces in enterprise environments. These ports aren\u0026rsquo;t open because someone forgot to close them. They\u0026rsquo;re open because the architecture requires it, and nobody goes back to add restrictions after the dashboards are working.\u003c/p\u003e\n\u003cp\u003eThe real mitigation isn\u0026rsquo;t binding to localhost \u0026ndash; it\u0026rsquo;s host-level firewalling. \u003ccode\u003eiptables\u003c/code\u003e, \u003ccode\u003enftables\u003c/code\u003e, or whatever host firewall your environment runs, scoped to allow only the specific source IPs that need access to each port. Prometheus scrapes Node Exporter? Allow 9100 from the Prometheus host only. Grafana queries Prometheus? Allow 9090 from the Grafana host only. Everything else gets dropped. That\u0026rsquo;s straightforward to implement and it actually matches how these stacks are deployed, instead of pretending everything can live on loopback.\u003c/p\u003e\n\u003cp\u003eWe\u0026rsquo;re leaving them wide open here for the same reason we\u0026rsquo;re running HTTP: you need to see the exposure before you close it.

OAuth user provisioning uses email + auth_id as a compound identifier, and the stale record blocked the legitimate user. Fix: delete the conflicting user in Grafana\u0026rsquo;s admin UI. Broader lesson: never test OAuth with admin accounts. Always use dedicated test users.\u003c/p\u003e\n\u003chr\u003e\n\u003ch2 id=\"whats-deployed-and-whats-exposed\"\u003eWhat\u0026rsquo;s Deployed and What\u0026rsquo;s Exposed\u003c/h2\u003e\n\u003cp\u003e\u003ca href=\"/images/attack-surface-map.jpg\"\u003e\u003cimg alt=\"Pre-hardening attack surface map showing all exposed ports, plaintext credential paths, and missing security controls\" loading=\"lazy\" src=\"/images/attack-surface-map.jpg\"\u003e\u003c/a\u003e\u003c/p\u003e\n\u003cp\u003eThe stack is functional. Authentik handles authentication, Grafana serves dashboards with role-based access, Prometheus scrapes metrics from four exporters, and group-based policy enforcement denies access to users outside the permitted groups.\u003c/p\u003e\n\u003cp\u003eNow here\u0026rsquo;s what an attacker sees, and why we built it this way first. All traffic is plaintext HTTP across VLANs \u0026ndash; anyone with a packet capture on either segment reads every OAuth token exchange, every Prometheus query, every dashboard session. The OAuth client secret sits in a plaintext \u003ccode\u003e.env\u003c/code\u003e file readable by anyone with shell access to the host. Grafana is directly exposed on port 3000 with no reverse proxy filtering requests. Prometheus and all four exporters are network-accessible with zero authentication \u0026ndash; that\u0026rsquo;s unauthenticated access to host metrics, container metadata, and endpoint probe results. Default Grafana sessions persist indefinitely, so a stolen session cookie works until the server restarts. No container capability dropping, no resource limits, no automated backups, no centralized audit logging.\u003c/p\u003e\n\u003cp\u003eThat\u0026rsquo;s a lot of exposure. That\u0026rsquo;s also what a vanilla deployment of these tools looks like in most environments, except most environments don\u0026rsquo;t write it down. We\u0026rsquo;re going to fix each of these systematically and document why.\u003c/p\u003e\n\u003cp\u003eThe next post walks through these vulnerabilities in detail \u0026ndash; what an attacker can actually reach, what data they can pull, and how each exposure gets exploited in practice \u0026ndash; then covers the hardening steps to close them. That means locking down exposed ports, adding HAProxy for TLS termination, configuring session timeouts, dropping container capabilities, and restricting the monitoring exporters to Docker-internal networks.\u003c/p\u003e\n\u003cp\u003eOpenBAO gets its own dedicated series. PKI certificate automation, runtime secret injection for OAuth credentials, Prometheus auth token provisioning \u0026ndash; that\u0026rsquo;s a substantial deployment with its own architecture decisions and failure modes. Cramming it into a hardening post would do it a disservice.\u003c/p\u003e\n\u003chr\u003e\n\u003ch2 id=\"quick-reference\"\u003eQuick Reference\u003c/h2\u003e\n\u003ch3

Ollama serves models to anyone who knocks. Open WebUI\u0026rsquo;s Direct Connections feature hands a rogue model server the keys to your users\u0026rsquo; browsers.

This one is about doing things right.\u003c/p\u003e\n\u003cp\u003eBy the end of Part I, a PII masking layer is deployed, configured, and verified to work when explicitly invoked. Names become \u003ccode\u003e\u0026lt;PERSON\u0026gt;\u003c/code\u003e. Emails become \u003ccode\u003e\u0026lt;EMAIL_ADDRESS\u0026gt;\u003c/code\u003e. Credit cards become \u003ccode\u003e\u0026lt;CREDIT_CARD\u0026gt;\u003c/code\u003e. The masking works. The logs confirm it.\u003c/p\u003e\n\u003cp\u003eWhat the logs also confirm \u0026ndash; once you know where to look \u0026ndash; is that Presidio never fired on a single real user request. Not once.

Open WebUI routes all model requests through LiteLLM instead of directly to Ollama. LiteLLM intercepts each prompt, calls Presidio to detect and replace PII, and forwards the cleaned version to Ollama.

The environment variables satisfy the startup validation.

The guardrails v2 syntax (\u003ccode\u003eguardrails:\u003c/code\u003e block in config) was introduced after v1.40.12.

The health check sits waiting. \u003ccode\u003ecreate_app()\u003c/code\u003e finishes. The worker tries to respond to the health check. The health check connection has timed out.
