What is CVE-2025-8267?

The ssrfcheck package prior to version 1.2.0 is susceptible to Server-Side Request Forgery (SSRF) due to an incomplete denylist of invalid IP address ranges. Notably, the package inaccurately allows access to the multicast IP address space 224.0.0.0/4. This vulnerability enables attackers to generate crafted requests that target these multicast addresses, potentially compromising system integrity and security.
