CVE-2026-88000 · Open WebUI: Any authenticated user can hang the server via message deletion in a cyclic chat tree
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.10.0 until 0.11.1, DELETE /api/v1/chats/{id}/messages/{message_id} used the chat-history deletion helper in backend/open_webui/models/chats.py to follow childrenIds without recording visited message identifiers. An authenticated user could store a cyclic chat tree and delete a message, causing a synchronous infinite loop on the server request loop that blocked every user's requests until the process was killed. This issue is fixed in version 0.11.1.
