medium Tenable Cloud Security Plugin ID 447903

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.8.0 until
 0.9.0, Open WebUI's OAuth token exchange endpoint issues a session for a provider access token without
 applying the email domain allowlist that the normal OAuth login callback enforces. An account whose email
 domain the login callback would refuse could still obtain a working session through this endpoint. This

Solution

Update the open-webui library and its related packages to version 0.9.0 or later.
