Within 24 hours: Identify all GitLab instances running affected versions (18.2 before 18.6.6, 18.7 before 18.7.4, 18.8 before 18.8.4) and assess Web IDE usage patterns. Within 7 days: Implement network-level restrictions to limit Web IDE access to trusted internal networks only, disable Web IDE if not operationally necessary, and monitor token generation logs for unauthorized activity. Within 30 days: Upgrade to patched versions (18.6.6+, 18.7.4+, or 18.8.4+) once available, rotate all potentially exposed tokens, and conduct a repository access audit to detect unauthorized clones or downloads.
