CVE-2026-9559

A path traversal vulnerability exists in the campaign import feature of Mautic 7. When extracting uploaded ZIP files during campaign imports, a flaw in the validation logic allows file paths to escape the intended temporary directories. An authenticated user with campaign import privileges (campaign:imports:create) can write arbitrary PHP files to sensitive system directories. An attacker can exploit this to overwrite critical internal configuration or cache components, resulting in Remote Code Execution (RCE) under the context of the web server user.

Summary		(es) Una vulnerabilidad de salto de ruta existe en la función de importación de campañas de Mautic 7. Al extraer archivos ZIP subidos durante las importaciones de campañas, un fallo en la lógica de validación permite que las rutas de archivo escapen los directorios temporales previstos. Un usuario autenticado con privilegios de importación de campañas (campaign:imports:create) puede escribir archivos PHP arbitrarios en directorios sensibles del sistema. Un atacante puede explotar esto para sobrescribir componentes críticos de configuración interna o de caché, lo que resulta en Ejecución Remota de Código (RCE) bajo el contexto del usuario del servidor web.
