CVE-2021-34643Network attack vector

Browser script execution via unescaped request path

Published Aug 16, 2021 · Updated May 5, 2025

Reflected XSS in Skaut bazar 1.3.2 and earlier allows remote attackers to inject browser-executed scripts through crafted URLs. The plugin renders PHP's $_SERVER['PHP_SELF'] value in skaut-bazar.php without neutralizing attacker-controlled path content. Exploitation requires a user to follow a malicious link, after which script code runs in that user's browser under the affected site's origin.
