An issue has been discovered in GitLab CE/EE affecting all versions from 16.8 before 17.10.7, 17.11 before 17.11.3, and 18.0 before 18.0.1. Group access controls could allow certain users to bypass two-factor authentication requirements.
Weakness
The product uses an authentication mechanism to restrict access to specific users or identities, but the mechanism does not sufficiently prove that the claimed identity is correct.
