Technical details
This is an unauthenticated server-side request forgery (SSRF) vulnerability in OpenPanel before 2.3.0. The /misc/favicon and /misc/og endpoints accept a user-supplied URL parameter with insufficient validation—only checking for http/https protocols but allowing access to private IP ranges and internal hostnames. The fetchImage() function follows redirects without filtering, allowing bypass of the image-extension check. Small responses (under 5 KB for /favicon, under 10 KB for /og) are returned verbatim to the attacker, enabling credential theft from cloud metadata endpoints and enumeration of internal services. No authentication is required; the endpoints are mounted without auth preHandlers.
