CVE-2020-10074 is a security vulnerability affecting GitLab versions 10.1 through 12.8.1, discovered and disclosed in March 2020. The vulnerability involves incorrect access control that could allow an attacker to take over a GitLab account through an expired link. This security issue was responsibly reported by security researcher @gnux (GitLab Release).

The vulnerability stems from an incorrect access control implementation in GitLab that allowed account takeover through expired links. The issue affects GitLab installations from version 10.1 up to version 12.8.1. The vulnerability was patched in GitLab versions 12.8.2, 12.7.7, and 12.6.8 (GitLab Release).
