Internal HTTP response disclosure via unrestricted URL fetching
Published Sep 4, 2026 · Updated Sep 4, 2026
Server-side request forgery in light0011 cms UEditor allows remote attackers to read internal HTTP responses through the catchimage endpoint. The unauthenticated handler passes each source[] URL to Uploader, which accepts HTTP prefixes and calls get_headers() and readfile() without destination controls before writing the body under a public upload path. No authentication is required; affected deployments let remote attackers probe reachable internal services and retrieve compatible response bodies.
