Open WebUI: Realtime endpoints accept Redis-revoked JWTs after signout/backchannel logout

Published Jul 9, 2026 · Updated Jul 9, 2026 · Assigned by GitHub_M

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.
