      "value": "CI4MS is a CodeIgniter 4-based CMS skeleton that delivers a production-ready, modular architecture with RBAC authorization and theme support. Prior to version 0.31.5.0, ci4ms Backup::restore extracts user uploaded ZIP archives without validating entry names, allowing an authenticated backend user with the backup create permission to write files to arbitrary filesystem locations (Zip Slip) and achieve remote code execution by dropping a PHP file under the public web root. This issue has been patched in version 0.31.5.0."

Antes de la versión 0.31.5.0, ci4ms Backup::restore extrae archivos ZIP subidos por el usuario sin validar los nombres de las entradas, permitiendo a un usuario autenticado del backend con el permiso de creación de copia de seguridad escribir archivos en ubicaciones arbitrarias del sistema de archivos (Zip Slip) y lograr la ejecución remota de código al colocar un archivo PHP bajo la raíz web pública.
