Overview
open-webui is an Open WebUI
Affected versions of this package are vulnerable to Protection Mechanism Failure via the profile_image_url field in the model metadata process. An attacker can execute arbitrary JavaScript in the context of another user's session by storing a crafted SVG payload as a model's profile image and enticing a victim to open the image URL as a top-level document. This enables theft of authentication tokens and full account compromise. This is only exploitable if a victim user opens the model profile image URL directly in a new browser tab or window.
