CVE-2017-6534
A Cross-Site Scripting (XSS) issue was discovered in webpagetest 3.0.
Does this matter?
Lower severity and a low EPSS score (0.64%). Track it; it rarely justifies an emergency change on its own.

The vulnerability exists due to insufficient filtration of user-supplied data (pssid) passed to the webpagetest-master/www/pss.php URL.
