CVE-2024-2800 is a regular expression denial-of-service vulnerability in GitLab Community Edition and Enterprise Edition. The flaw is in RefMatcher logic used when matching branch names with wildcard patterns. A crafted branch name or matching input can trigger excessive regular-expression backtracking, causing disproportionate CPU consumption during evaluation. The issue affects GitLab CE/EE versions from 11.3 before 17.0.6, 17.1 before 17.1.4, and 17.2 before 17.2.2.
