Official Description
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 11.10 before 18.8.7, 18.9 before 18.9.3, and 18.10 before 18.10.1 that could have allowed an authenticated user to perform unauthorized actions on merge requests in other projects due to improper access control during cross-repository operations.
Technical Analysis
CVE-2026-2726 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
