GHSA-W2RX-84HP-GG95
Vulnerability from github – Published: 2026-08-04 19:40 – Updated: 2026-08-04 19:40Summary
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 page could use its own JavaScript to reach addresses the validation exists to block. Because the loader returns the page's final DOM to the requesting user, anything the page read back from those addresses ends up in the web-search or RAG output.
Preconditions
WEB_LOADER_ENGINE=playwright. This is not the default; deployments on the default web loader are unaffected.- A reachable Playwright browser, either local or via
PLAYWRIGHT_WS_URL. - Any authenticated user who can submit a URL for ingestion or trigger a web search. No administrator role is required.
- Something worth reading on a network the browser can reach. A deployment whose browser container has no route to internal services loses nothing here.
Impact
An authenticated user can read HTTP responses from services reachable by the browser process: cloud instance metadata, other containers on the same network, and internal APIs bound to private addresses. The content is returned to the user through the normal web-search or document-ingestion result, so this is a read primitive, not a blind one. It confers no write access and no availability impact, and it does not extend beyond what the browser's network position already allows.
Fix
Fixed in 0.11.0 by commit bef63a2ae. Every intercepted request is now validated, fetched with redirects disabled, re-validated on each redirect hop and then fulfilled, so neither a sub-resource nor a redirect can land on a non-global address. The same change blocks the two paths that never reached the interceptor at all: service-worker requests, via service_workers="block", and WebSocket connections, via a route handler that never connects upstream. Upgrading to 0.11.0 fully resolves the issue; no configuration change is required.
Root cause
Affected component: SafePlaywrightURLLoader in backend/open_webui/retrieval/web/utils.py, in both the sync and async request interceptors. Affected setup: only builds running the Playwright loader engine.
The interceptor was written to guard navigation, and its first action was to return early for any request whose resource type was not document. The intent was that only the page the user asked for needs address validation, but a browser page is not a single request: once the validated document loads, its scripts issue further requests under the page's own control, and those never reached the validation. The address check was therefore applied to the one request the attacker did not need to control, and skipped on every request they did.
Proof of concept
Reported against 0.10.2 by driving the interceptor directly with stand-in route and request objects, one call per resource type, against http://169.254.169.254/latest/meta-data/. The document type is aborted; every other type is continued unvalidated. The browser and the network request were seeded rather than driven end to end; the code path exercised is the one the browser reaches for each sub-resource.
Credits
- @edwardav970 — identified that address validation was applied only to the top-level document request, leaving every sub-resource type unvalidated.

CAPEC-664: Server Side Request Forgery
An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
