Name of the Vulnerable Software and Affected Versions infaveo-helpdesk versions 1.11.0 and below

Description A cross-site scripting (XSS) issue allows remote attackers to inject arbitrary web script or HTML via the $ SERVER["PHP SELF"] parameter in the dompdf/dompdf/www/demo.php file. This enables attackers to execute malicious scripts on the victim's browser.

As a temporary workaround, avoid using the $ SERVER["PHP SELF"] parameter in the affected file to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
