CVE-2026-34569
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 creating or editing blog categories. An attacker can inject a malicious JavaScript payload into the category title field, which is then stored server-side. This stored payload is later rendered unsafely across public-facing blog category pages, administrative interfaces, and blog post views without proper output encoding, leading to stored 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 crear o editar categorías de blog. Un atacante puede inyectar una carga útil de JavaScript maliciosa en el campo del título de la categoría, la cual se almacena luego en el servidor. Esta carga útil almacenada se renderiza posteriormente de forma insegura en las páginas de categorías de blog de cara al público, interfaces administrativas y vistas de publicaciones de blog sin una codificación de salida adecuada, lo que lleva a cross-site scripting (XSS) almacenado. Este problema ha sido parcheado en la versión 0.31.0.0."
