Summary
ssrfcheck has Incomplete IP Address Deny List that leads to Server-Side Request Forgery Vulnerability
Details

Versions of the package ssrfcheck below 1.2.0 are vulnerable to Server-Side Request Forgery (SSRF) due to an incomplete denylist of IP address ranges. Specifically, the package fails to classify the reserved IP address space 224.0.0.0/4 (Multicast) as invalid. This oversight allows attackers to craft requests targeting these multicast addresses.

Severity ?
