Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Open WebUI versions before 0.9.3 are vulnerable to cross-site request forgery through image URLs. An authenticated user can set an image URL, such as a profile or model picture, to an attacker-controlled endpoint, and any user who views that image sends a GET request to it, which can expose cookies and user details or cause denial of service. Upgrade to Open WebUI 0.9.3 or later. The source gives few details on other workarounds.
