Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.5.0 until 0.11.0, the standard channel message update and delete handlers accepted any caller holding write access on the channel without checking that the caller wrote the message. Because write access is the same grant a member needs to post, any ordinary participant in a shared standard channel could rewrite or permanently delete another participant message, while group and direct message handlers enforced authorship. This issue is fixed in 0.11.0.
Update open-webui to 0.11.0 if you use the affected versions. Test the change in a non-production environment first.

Severity is medium. Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform.

This issue is fixed in 0.11.0.
AI coding agents often install or upgrade packages automatically in generic and pip. A medium vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
