Overview

A privilege escalation vulnerability (CVE-2024-1299) was discovered in GitLab affecting versions 16.8 prior to 16.8.4 and 16.9 prior to 16.9.2. The vulnerability allowed users with a custom role of 'managegroupaccess_tokens' to rotate group access tokens with owner privileges (GitLab Security, Debian Tracker).
