The vulnerability allows a remote user to perform server-side requests to arbitrary URLs.

The vulnerability exists due to server-side request forgery (SSRF) in the API Extension API endpoint when handling API extension configuration requests. A remote user can send a specially crafted request with an attacker-controlled api_endpoint value to perform server-side requests to arbitrary URLs.
