CVE-2025-8267 | BDVDB-2026-287679 Detail

ssrfcheck

Description#

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.

Impact#

Per CVSS v3.1: confidentiality impact high, integrity impact low, availability impact none. Attack vector: network.
