Gitlab · Gitlab Ce/Ee · CVE-2021-22254
**Name of the Vulnerable Software and Affected Versions**
GitLab CE/EE versions 13.1 through 14.1.2
GitLab CE/EE version 14.0.7
GitLab CE/EE version 13.12.9
**Description**
The issue is related to a lack of proper output encoding or escaping in GitLab, a platform for collaborative code development. Under specific conditions, a user could be impersonated using GitLab shell. This allows a remote attacker to gain access to confidential data.
**Recommendations**
For GitLab CE/EE versions 13.1 through 14.1.2, update to a version outside of this range to resolve the issue.
For GitLab CE/EE version 14.0.7, update to a newer version to mitigate the risk.
For GitLab CE/EE version 13.12.9, update to a newer version to mitigate the risk.
As a temporary workaround, consider restricting access to the GitLab shell until a patch is available.
