Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.8.0, the profile_image_url field on the user profile update form accepted arbitrary data: URI values without MIME-type validation, resulting in a XSS vulnerability. This vulnerability is fixed in 0.8.0.
