CVE-2024-12156Network attack vector

Reflected XSS via unescaped page parameter

Published Dec 12, 2024 · Updated Apr 8, 2026

Reflected XSS in QuantumCloud SEO Help 6.1.3 and earlier allows remote attackers to inject script through the page parameter. The scan-results table header in inc/scan-list-scan-table-header-results.php outputs that query value without sufficient sanitization or contextual escaping. Execution requires a user to follow a crafted link and load the affected plugin page, exposing that user's browser session to attacker-controlled script.
