Vulnerability details
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input with API implementation. A remote non-authenticated attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems, when requests to the internal network for webhooks are enabled.
