CVE-2026-84249Network attack vector

Unauthenticated execution of arbitrary management operations

Published Oct 8, 2026 · Updated Oct 8, 2026

Authentication bypass in IBM Guardium Data Protection 12.2 and 12.2.2 allows remote attackers to run management operations. IBM identifies missing authentication for a critical function but does not disclose the affected endpoint, function, or request format. Exploitation requires network access without credentials or user interaction; the reported consequence is arbitrary management operations, not specifically operating-system command execution.
