The version of GitLab installed on the remote host is affected by a vulnerability, as follows:

  • An issue has been discovered in GitLab affecting all versions starting from 10.0 before 16.1.5, all versions starting from 16.2 before 16.2.5, all versions starting from 16.3 before 16.3.1. Due to improper permission validation it was possible to edit labels description by an unauthorised user. (CVE-2023-0120)
