CVE-2026-44174

Kirby is an open-source content management system. Prior to 4.9.1 and 5.4.1, Kirby did not validate the model attributes that were used in its collection queries, allowing attackers to include arbitrary model methods in their queries. This includes methods with sensitive data such as password() (disclosing the password hash) or root() (disclosing the absolute filesystem path on the server) as well as methods that perform impactful actions such as loginPasswordless() (causing a privilege escalation to another user) or delete() (deleting all queried models in one go if the authenticated user has appropriate permissions). This issue has been fixed in versions 4.9.1 and 5.4.1.

Summary		(es) Kirby es un sistema de gestión de contenido de código abierto. Antes de las versiones 4.9.1 y 5.4.1, Kirby no validaba los atributos del modelo que se utilizaban en sus consultas de colección, lo que permitía a los atacantes incluir métodos de modelo arbitrarios en sus consultas. Esto incluye métodos con datos sensibles como password() (revelando el hash de la contraseña) o root() (revelando la ruta absoluta del sistema de archivos en el servidor), así como métodos que realizan acciones de impacto como loginPasswordless() (causando una escalada de privilegios a otro usuario) o delete() (eliminando todos los modelos consultados de una sola vez si el usuario autenticado tiene los permisos adecuados). Este problema ha sido solucionado en las versiones 4.9.1 y 5.4.1.
