Description
A server-side request forgery vulnerability in Pinry through 2.1.13 allows unauthenticated remote attackers to make the server issue HTTP requests to arbitrary internal or external hosts via the pin-from-URL feature. The feature passes the user-supplied URL directly to requests.get() without host or IP validation, and ALLOW_NEW_REGISTRATIONS defaults to true enabling anonymous triggering. An attacker can reach internal services or cloud metadata endpoints from the server.
