CVE-2026-59219 Details
Description
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.0 before 0.10.0 with Redis configured, Socket.IO connect, user-join, join-channels, join-note, and the terminal websocket first-message authentication used decode_token without the Redis-backed is_valid_token revocation check, allowing revoked JWTs to continue authenticating realtime connections. This issue is fixed in version 0.10.0.
A vulnerability in Open WebUI versions 0.9.0 prior to 0.10.0, with Redis configured, allows revoked JSON Web Tokens (JWTs) to continue authenticating realtime WebSocket connections. The issue arises because the first-message authentication for the terminal WebSocket and several Socket.IO events does not check for token revocation. This flaw enables a revoked token to maintain access to realtime features, such as collaborative notes and terminal server interactions, despite being correctly invalidated in HTTP requests.
Users can update to Open WebUI version 0.10.0 or later, where this vulnerability is fixed. The update applies the JWT revocation check to the affected realtime WebSocket authentication processes, ensuring that revoked tokens are properly rejected.
