Machine-written summary

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

Open WebUI versions before 0.9.0 are vulnerable to server-side request forgery through the OAuth profile picture URL handling in the _process_picture_url function. An attacker who controls the picture claim from a configured OIDC provider can make the server fetch arbitrary URLs, including internal services, and read the response back through the stored profile image. Upgrade to Open WebUI 0.9.0 or later.
