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.
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.
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Gitlab | Gitlab | 16.8.0 (including) | 17.10.7 (excluding) |
| Gitlab | Gitlab | 17.11.0 (including) | 17.11.3 (excluding) |
| Gitlab | Gitlab | 18.0.0 (including) | 18.0.0 (including) |
| Gitlab | Ubuntu | esm-apps/xenial | * |
Attackers may be able to bypass weak authentication faster and/or with less effort than expected.
