Does this matter?

Lower severity and a low EPSS score (0.25%). Track it; it rarely justifies an emergency change on its own.

Description

QuickCMS is vulnerable to Reflected XSS via sSort parameter in admin's panel functionality. A malicious attacker can craft a specially crafted URL that, when opened, results in arbitrary JavaScript execution in the victim's browser. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.8 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.
