Summary

Open WebUI from 0.9.6 to 0.11.0, with WEB_LOADER_ENGINE=playwright, validates only the top-level page request and lets sub-resource requests pass unvalidated. A page supplied by an authenticated user can use JavaScript to reach blocked internal addresses, and returned DOM can include data read from those addresses in web-search or RAG output.

Risk Assessment

This could lead to disclosure of internal information or bypass of network security controls.

Recommendation

Upgrade Open WebUI to version 0.11.0 or later, which includes the fix.
