Description

The HCL BigFix SCM Reporting site contains an outdated and unsupported version of the jQuery 1.x library. Since jQuery 1.x has reached end-of-life and no longer receives security updates, it may expose the application to publicly known security weaknesses and increase the risk of client-side attacks such as Cross-Site Scripting (XSS) or manipulation through vulnerable third-party components.
