Open WebUI: Inaccessible knowledge bases are exposed through the built-in knowledge tool on most vector backends

SummaryThe built-in knowledge search tool returns knowledge bases the calling user has no access to. The tool works out which knowledge bases the caller may read and hands that set to the vector store as a search filter, and that filter is the only access control on the path. Most of the shipped...

Open WebUI: Non-admin users can delete admin-owned external knowledge connections via knowledge base deletion

SummaryExternal knowledge connections are created and owned by administrators, and are shared by every external knowledge base bound to them. Deleting an external knowledge base also removed that connection from the instance configuration, with no check on the caller's role and no check for other...
