      "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 0.31.0.0, the application fails to properly sanitize user-controlled input when creating or editing blog posts. An attacker can inject a malicious JavaScript payload into blog post content, which is then stored server-side. This stored payload is later rendered unsafely in multiple application 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 publicaciones de blog. Un atacante puede inyectar una carga útil (payload) de JavaScript maliciosa en el contenido de una publicación de blog, que luego se almacena en el servidor. Esta carga útil almacenada se renderiza posteriormente de forma insegura en múltiples vistas de la aplicación 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."
