AnalysisAIv1 – Jul 27, 2026

Information disclosure in Open WebUI versions 0.7.0 through 0.9.x allows authenticated channel members to retrieve sensitive administrator settings, including API keys for tool servers and webhook configurations. The /api/v1/channels/{id}/members endpoint fails to sanitize user model responses, exposing full UserModel data to any participant in a shared channel. A public proof-of-concept exists, but active exploitation is not confirmed and the EPSS probability of widespread exploitation is low (0.26%).
