CVE-2025-8267: Felipperegazio Ssrf Check

Medium severity, CVSS 5.3. EPSS: 0.5% chance of exploitation in the next 30 days.

Versions of the package ssrfcheck before 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.

Affected products

• Felipperegazio Ssrf Check: before 1.2.0 (fixed in 1.2.0)
