NVD description
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, channel thread parent and reply handling did not bind parent_id to the channel in the URL, allowing an authenticated user to reference a message from another private or DM channel and disclose thread context across channels. This issue is fixed in version 0.10.0.
What to do
- Upgrade Open WebUI to
0.10.0or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
