CVE-2026-59714 · Open WebUI: Cross-channel message overwrite via chat completion API (single-model and multimodel message_ids)
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 0.9.5 before 0.10.0, any authenticated user can overwrite the content of a message in a channel they do not belong to (including private and DM channels) by sending a chat completion request with a channel:-prefixed chat_id and a target message_id. The channel: path routes pipeline output through _make_channel_emitter, which writes to the Messages table using the caller-supplied message_id without binding it to the channel. This issue is fixed in version 0.10.0.
