Name of the Vulnerable Software and Affected Versions GitLab CE/EE versions 14.0 and later

Description The issue is related to a stored cross-site-scripting vulnerability in GitLab CE/EE, which can be exploited via a specifically crafted default branch name. This allows a remote attacker to impact data integrity due to the lack of filtering of the default branch name field.
