Authenticated browser script execution

Published Nov 28, 2025 · Updated Nov 28, 2025

Cross-site scripting in HCL Technologies Unica 12.0.0 allows remote authenticated users to execute script in the application origin. Neither the CVE record nor the linked disclosure identifies the affected page, parameter, or missing output-neutralization operation. A low-privileged account is required; successful exploitation can read or modify limited application data but does not interrupt service.
