Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Open WebUI, all versions up to and including 0.7.2, has a blind server-side request forgery in its image edit feature, where a user-supplied URL is fetched by the server with no domain or local-address restriction. An attacker with access to that feature can use it to probe internal hosts and ports, since the response cannot be read but success or failure reveals whether a port is open. No fixed version is listed; restricting image URLs to exclude local and private addresses would reduce the risk.
