Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Open WebUI versions 0.9.6 up to but not including 0.11.0 are vulnerable when the Playwright web loader is enabled. The address check applied only to the top-level page request, so scripts on a page could make other requests to internal addresses and read the responses, which then appeared in web search or RAG results. An authenticated user who can submit URLs or run a web search could read data from services reachable by the browser, such as cloud metadata or internal APIs. Upgrade to Open WebUI 0.11.0. The default web loader is not affected.
