CVE-2020-10083Network attack vector

Unauthorized project access via unapplied group changes

Published Mar 13, 2020 · Updated Aug 4, 2024

Improper permission preservation in GitLab 12.7 through 12.8.1 allows remote attackers to retain project access after group changes. GitLab has not published the affected code locus; under an undisclosed group-related condition, it fails to apply a project authorization change. The required group configuration is undisclosed, and retained authorization permits access to project data after permissions should have changed.
