What is CVE-2025-11990?

GitLab EE has addressed a critical issue related to Cross-Site Request Forgery (CSRF) vulnerabilities, impacting all versions from 18.4 prior to 18.4.4, and 18.5 before 18.5.2. This vulnerability allowed authenticated users to exploit weaknesses in input validation of repository references, leading to the potential unauthorized retrieval of CSRF tokens. Such exploits stem from improper handling of redirects when processing requests, thereby compromising the integrity of user sessions and allowing attackers to perform unauthorized actions on behalf of legitimate users.

Affected Version(s)

GitLab 18.4 < 18.4.4

GitLab 18.5 < 18.5.2
