Name of the Vulnerable Software and Affected Versions GitLab CE/EE versions 11.8 and later

Description The issue is related to the possibility of creating a recursive pipeline relationship, which can lead to a denial of service. This can be exploited by a remote attacker to cause resource exhaustion.

Recommendations For GitLab CE/EE versions 11.8 and later, consider restricting pipeline relationships to prevent recursive connections until a patch is available. As a temporary workaround, limit resource allocation to pipelines to minimize the risk of exhaustion. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
