GHSA-M3QF-58WF-W979 Open WebUI: Arena task endpoints can bypass underlying model access controls
Summary An authenticated non-admin user with read access to an arena wrapper model can reach a restricted underlying model through task endpoints such as /api/v1/tasks/moa/completions. The normal chat route resolves arena models before the final chat dispatch and therefore re-checks the selected...
GHSA-2XWM-4H2Q-GGFX Open WebUI: Model meta.knowledge read-only file access can be upgraded to file write/delete
Summary Current main and v0.9.6 still allow an authenticated user to turn read-only access to another user's file into write/delete access by attaching that file ID to an attacker-controlled workspace model. This is an incomplete-fix variant of GHSA-vjqm-6gcc-62cr. The current fix adds...
