CVE-2021-22253

Name of the Vulnerable Software and Affected Versions GitLab EE versions 13.4 and later

Description The issue is related to improper authorization, allowing a user who previously had necessary access to trigger deployments to protected environments under specific conditions, even after their access has been removed. This can lead to data integrity issues and potentially cause a denial of service.

Recommendations For GitLab EE versions 13.4 and later, update to a version that includes the fix for this issue to prevent exploitation. As a temporary workaround, consider restricting access to protected environments to minimize the risk of unauthorized deployments.
