93
FAUCET Score

CVE-2021-22175 is a critical Server-Side Request Forgery (SSRF) vulnerability in GitLab, affecting all versions from 10.5 onwards. This flaw allows unauthenticated attackers to exploit GitLab instances, even when user registration is disabled, by manipulating webhook requests to the internal network. With a CVSS score of 9.8 (Critical), it presents a severe risk due to its network-based attack vector, low attack complexity, and high potential for confidentiality, integrity, and availability compromise. The vulnerability is actively exploited in the wild, as confirmed by its inclusion in CISA's KEV catalog, and has garnered significant community discussion and media coverage, though no public Metasploit or ExploitDB modules are currently available.
