CVE-2025-66444Network attack vector

Authenticated script execution via undisclosed cross-site scripting

Published Dec 24, 2025 · Updated Dec 24, 2025

Cross-site scripting in Hitachi Infrastructure Analytics Advisor and Ops Center Analyzer allows remote authenticated users to run browser scripts. Hitachi identifies the affected loci as Data Center Analytics and Analyzer detail view but has not disclosed which input reaches an HTML response without safe neutralization. Exploitation requires low-privileged access and user interaction; successful script execution exposes browser-accessible data and can alter the victim's session context.
