Machine-written summary

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

Open WebUI versions 0.10.0 up to but not including 0.11.1 are affected. A user who holds a write grant on an external knowledge base can delete it, which also removes the admin-created external connection it uses, breaking other knowledge bases bound to that connection. Upgrade to version 0.11.1, which is the fixed version; no workaround is listed.
