How the mentioned CVE works:
This CVE-2025-22094 is a reflected Cross-Site Scripting (XSS) vulnerability in MCMS v6.0.1. The application fails to properly sanitize user-supplied input in one or more of its HTTP request parameters. When an attacker crafts a malicious URL containing a JavaScript payload and tricks a user into clicking it, the application reflects the payload back in the HTTP response without encoding or validation. The user’s browser then receives and executes this malicious script. Since the script runs in the context of the victim’s session, the attacker can potentially steal session cookies, perform actions on behalf of the user, or deface the website, all without direct access to the application’s backend.
