Official Description
GitLab has remediated an issue in GitLab EE affecting all versions from 16.10 before 18.9.7, 18.10 before 18.10.6, and 18.11 before 18.11.3 that when instance-level approval rule editing prevention was enabled, could have allowed an authenticated user with Maintainer permissions to modify or delete project approval rules due to missing authorization checks.
Technical Analysis
CVE-2026-2900 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
