Name of the Vulnerable Software and Affected Versions webpagetest version 3.0

Description A Cross-Site Scripting (XSS) issue exists due to insufficient filtration of user-supplied data (pssid) passed to the "webpagetest-master/www/pss.php" URL. This allows an attacker to execute arbitrary HTML and script code in a browser in the context of the vulnerable website.

Recommendations For webpagetest version 3.0, ensure proper filtration of user-supplied data, especially the pssid parameter, to prevent arbitrary code execution. As a temporary workaround, consider restricting access to the "webpagetest-master/www/pss.php" URL until a proper fix is applied.
