Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Open WebUI versions up to and including 0.9.5 are vulnerable to stored cross-site scripting through model profile images. An authenticated user with the workspace.models permission, which is enabled by default, can store an SVG image containing script in a model's profile image. If a victim opens that image URL directly, the script can run in the Open WebUI origin and read the victim's session token, enabling account takeover. Upgrade to Open WebUI 0.9.6, which contains the fix.
