CVE-2026-45666 · Open WebUI: Indirect Object Reference (IDOR) in user notes
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.8.11, the API /api/v1/notes/{note_id} endpoint lacks proper authorization checks, allowing authenticated users to retrieve notes belonging to other users by guessing or enumerating UUIDs. This results in unauthorized disclosure of potentially sensitive or private user data. This vulnerability is fixed in 0.8.11.
