CVE-2026-70479 · Open WebUI: SSRF into internal services via unvalidated sub-resource requests in the Playwright web loader

This page contains facts from public vulnerability sources. Check the original advisory before updating.

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.6 until 0.11.0, with WEB_LOADER_ENGINE=playwright, the Playwright web loader 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. This issue is fixed in 0.11.0.
