CVE-2021-39322Network attack vector

Reflected XSS via unescaped request path

Published Sep 2, 2021 · Updated May 5, 2025

Reflected XSS in CyberNetikz Easy Social Icons 3.0.8 and earlier allows remote attackers to execute script via a crafted request path. The plugin's main PHP file writes the raw $_SERVER['PHP_SELF'] value into generated HTML without neutralizing attacker-controlled path content. Exploitation requires Apache with mod_php or another affected configuration and a victim who follows the crafted URL; the script then runs in the site's origin.
