CVE-2026-84075Network attack vector

Unauthenticated security bypass via ChangeTrackerServlet

Published Sep 18, 2026 · Updated Sep 18, 2026

Missing authentication in IBM Guardium Data Protection 12.2 allows remote attackers to bypass security restrictions through ChangeTrackerServlet. The servlet accepts security-critical requests without first requiring an authenticated session, but IBM has not disclosed which operations the endpoint exposes. Network access to the appliance is sufficient, while the specific data exposure, unauthorized changes, and service effects remain undisclosed.
