      "value": "Wazuh 4.0.0 before 4.14.6 contains a path traversal vulnerability that allows authenticated cluster peers to delete arbitrary directory contents by supplying a traversal-shaped node name in the cluster hello payload without validation. Attackers holding a valid cluster Fernet key can craft a malicious node name and disconnect, triggering the master's peer cleanup routine to remove the contents of arbitrary directories within the Wazuh installation path writable by the wazuh user."

      "value": "Wazuh 4.0.0 anterior a 4.14.6 contiene una vulnerabilidad de salto de ruta que permite a pares de clúster autenticados eliminar contenidos de directorio arbitrarios al proporcionar un nombre de nodo con forma de salto de ruta en la carga útil ’hello’ del clúster sin validación. Los atacantes que posean una clave Fernet de clúster válida pueden crear un nombre de nodo malicioso y desconectarse, lo que activa la rutina de limpieza de pares del maestro para eliminar el contenido de directorios arbitrarios dentro de la ruta de instalación de Wazuh que sean escribibles por el usuario wazuh."
