This measurement provides an estimate of reachable instances, not the exact count of vulnerable instances. Self-managed GitLab instances, especially those hosting credentials, can provide access to sensitive data and systems. The measurement helps prioritize response efforts by identifying exposed instances for patching and credential review.
Inventorying self-managed GitLab instances, verifying versions, upgrading to patched versions, restricting public reachability if upgrade is not immediate, and separately reviewing credentials are recommended actions.
