CyberRota Analysis
AI-GeneratedAuthenticated non-admin users with read access to an arena wrapper model in Open WebUI versions prior to 0.10.0 can exploit task endpoints to access restricted underlying models due to improper access controls. This vulnerability could lead to unauthorized data exposure, potentially compromising sensitive information. Organizations using affected versions should prioritize updating to version 0.10.0 to mitigate this risk.

Original NVD Description
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.8.12 before 0.10.0, 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 underlying model. The task routes call utils.chat.generate_chat_completion() directly. In that direct path, arena fallback resolution happens after the wrapper access check and then recurses with bypass_filter=True, skipping the selected submodel's access check. This issue is fixed in version 0.10.0.
