CVE-2026-34564
Full vulnerability record from the local CVENow database.
Description
CI4MS is a CodeIgniter 4-based CMS skeleton that delivers a production-ready, modular architecture with RBAC authorization and theme support. Prior to version 0.31.0.0, the application fails to properly sanitize user-controlled input when adding Pages to navigation menus through the Menu Management functionality. Page-related data selected via the Pages section is stored server-side and rendered without proper output encoding. This stored payload is later rendered unsafely within administrative interfaces and public-facing navigation menus, leading to stored DOM-based cross-site scripting (XSS). This issue has been patched in version 0.31.0.0.

"value": "CI4MS es un esqueleto de CMS basado en CodeIgniter 4 que ofrece una arquitectura modular, lista para producción, con autorización RBAC y soporte de temas. Antes de la versión 0.31.0.0, la aplicación no logra sanear correctamente la entrada controlada por el usuario al añadir Páginas a los menús de navegación a través de la funcionalidad de Gestión de Menús. Los datos relacionados con la página seleccionados a través de la sección Páginas se almacenan en el servidor y se renderizan sin una codificación de salida adecuada. Esta carga útil almacenada se renderiza posteriormente de forma insegura dentro de las interfaces administrativas y los menús de navegación públicos, lo que lleva a cross-site scripting (XSS) basado en DOM almacenado. Este problema ha sido parcheado en la versión 0.31.0.0."
