CVE-2026-84862Network attack vector

Authenticated code execution via Quartz deserialization

Published Sep 25, 2026 · Updated Sep 25, 2026

Insecure deserialization in IBM Guardium Data Protection 12.2 allows remote authenticated users to execute arbitrary code. The Quartz JDBC job store deserializes attacker-controlled job data without establishing that the serialized objects are safe. Exploitation requires a high-privileged authenticated account and can compromise confidentiality, integrity, and availability on the appliance.
