## Technical details

An Insufficiently Protected Credentials vulnerability (CWE-522) exists in GitLab EE's repository mirroring component. The flaw stems from improper authorization controls that fail to adequately restrict access to stored credentials under specific conditions. An authenticated attacker with 'Maintainer' role permissions can exploit this over the network to retrieve credentials belonging to other users. The issue affects GitLab EE versions 9.5 through 18.11.6, 19.0.x before 19.0.4, and 19.1.x before 19.1.2. GitLab has released patches in versions 18.11.7, 19.0.4, and 19.1.2 to remediate this behavior.

## Affected products

- GitLab GitLab EE 9.5 before 18.11.7, 19.0 before 19.0.4, 19.1 before 19.1.2
