CVE-2026-84106Network attack vector

Authenticated code execution via cross-site scripting

Published Sep 18, 2026 · Updated Sep 18, 2026

Cross-site scripting in IBM Guardium Data Protection 12.2 allows remote authenticated users to execute arbitrary code through the web interface. IBM identifies improper neutralization during web-page generation but does not disclose the affected page, parameter, or encoding failure. Exploitation requires low-privileged authentication and interaction by another user, with code executing in that user's browser context.
