GitLab has remediated an issue in GitLab EE affecting all versions from 18.6 before 18.8.9, 18.9 before 18.9.5, and 18.10 before 18.10.3 that under certain circumstances could have allowed an authenticated user with auditor privileges to modify vulnerability flag data in private projects due to incorrect authorization.
Analysis
GitLab EE versions 18.6-18.8.8, 18.9-18.9.4, and 18.10-18.10.2 allow authenticated users with auditor role privileges to modify vulnerability flag data in private projects due to improper authorization checks. The vulnerability requires valid GitLab credentials and auditor-level access but enables unauthorized data integrity compromise within project security contexts.
