Open WebUI: Any authenticated user can stall a worker via a knowledge-search pattern that backtracks catastrophically

Summary The built-in knowledge search tools let a chat participant choose the pattern used to grep knowledge files. Patterns containing regex metacharacters were compiled with Python's backtracking re engine and run against every line of every reachable file, with no time limit anywhere on that...

Open WebUI: Tool source code disclosed to read-only users via the tool list and get endpoints

Summary A workspace tool shared with a read grant returned its full Python source to the recipient. Any authenticated non-admin who could use a shared tool could also read its source, including any user on the instance when a tool was shared publicly. Source is meant to be a writer-only tier: the...

Open WebUI: Cross-user file content disclosure via request-scoped direct model knowledge metadata

Summary Open WebUI lets a client define a model inline on a chat request instead of selecting a saved workspace model. The knowledge attached to such an inline model was used as-is, without checking that the caller can read what it points at. Any authenticated user who knows another user's file i...

CVE-2026-70487 Open WebUI: Cross-user file content disclosure via request-scoped direct model knowledge metadata

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.8.8 until 0.11.0, inline direct model metadata accepted client-supplied knowledge attachments without filtering them against the caller's read access. Any authenticated user who knew another user's file i...

CVE-2026-70487

Open WebUI (versions 0.8.8–0.11.0) allowed client-supplied knowledge attachments in an inline model to bypass read access checks, enabling any authenticated user who knows another user’s file id to retrieve indexed chunks from that file via builtin knowledge tools. This caused read-only cross-use...

Open WebUI: Any authenticated user can reach internal services and cloud metadata via NAT64-encoded URLs

Summary Open WebUI fetches user-supplied URLs on the server for RAG URL ingestion, URL-to-markdown conversion and web-search content retrieval, and decides whether a destination is allowed by asking whether its IP address is globally routable. That test operates on the literal IPv6 address and do...

Open WebUI: Users denied the image-generation permission can still generate images via chat completions

Summary An authenticated user whose features.imagegeneration permission has been revoked can still make the server generate images by sending the feature flag in a chat-completion request. The chat pipeline took the client-supplied features object at face value and never re-checked the permission...

CVE-2026-70482 Open WebUI: Account takeover via OAuth token exchange accepting tokens issued to any client

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.8.0 until 0.11.0, when ENABLEOAUTHTOKENEXCHANGE=True, /oauth/provider/token/exchange accepts a raw provider access token and validates it by calling the provider userinfo endpoint without confirming which...

Open WebUI: SSRF into internal services via unvalidated sub-resource requests in the Playwright web loader

Summary With the Playwright web loader enabled, Open WebUI opens user-submitted URLs in a real browser and validates the destination address before allowing the request. That check only ran for the top-level page request. Every other request the page issued was passed through unvalidated, so a pa...
