Stored script execution via unsanitized article titles
Published Nov 24, 2025 · Updated Jul 5, 2026
Stored XSS in YCCMS 3.4 article management allows remote authenticated users to execute scripts in visitors' browsers via article titles. The add() and getPost() functions in ArticleAction.class.php store the title parameter without sufficient sanitization and later place it in rendered article content. Backend article-management access is required to plant the payload; viewing the affected article triggers it, exposing session data and permitting actions in the visitor's session.
