Description
Webstudio through 0.296.0 contains an unauthenticated server-side request forgery vulnerability in the /cgi/image, /cgi/video, and /cgi/asset proxy routes when RESIZE_ORIGIN environment variable is unset. Attackers can supply arbitrary URLs to these endpoints to read cloud instance metadata, access internal services, and perform network reconnaissance on the instance infrastructure.
