CVE-2024-1774Network attack vector

Unauthenticated stored XSS via unescaped cookie values

Published Apr 9, 2024 · Updated Apr 8, 2026

Stored XSS in Customily Product Personalizer 1.23.3 and earlier allows remote attackers to inject scripts through user cookies. The plugin accepts attacker-controlled cookie values and renders them into WordPress pages without sufficient sanitization or output escaping. Authentication is not required; the scripts execute in browsers that access an injected page, enabling page-content manipulation and access to browser-visible data.
