Description
OpenPanel before 2.3.0 contains an unauthenticated server-side request forgery vulnerability in the /misc/favicon and /misc/og endpoints that accept an attacker-supplied url parameter with insufficient validation. Attackers can force the API to fetch arbitrary internal hosts and cloud metadata endpoints, with small responses returned verbatim enabling credential theft and internal service enumeration.
