Loop with Unreachable Exit Condition ('Infinite Loop') in GitLab
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 17.1 before 18.6.4, 18.7 before 18.7.2, and 18.8 before 18.8.2 that under certain circumstances could have allowed an authenticated user to create a denial of service condition by configuring malformed Wiki documents that bypass cycle detection.
