CVE-2026-62354

Authorization handling for Parameter Context validation requests in Apache NiFi 1.10.0 through 2.10.0 allows clients with read access to submit proposed Parameter values. The proposed values override current configuration, enabling users with read access to invoke predefined component validation methods with alternative settings. Apache NiFi installations that do not implement different levels of authorization for viewing and modifying Parameter Context configuration are not subject to this vulnerability. Upgrading to Apache NiFi 2.11.0 is the recommended mitigation, requiring write access to submit Parameter Context validation requests.

Summary		(es) La gestión de la autorización para las solicitudes de validación de Contexto de Parámetros en Apache NiFi 1.10.0 hasta 2.10.0 permite a los clientes con acceso de lectura enviar valores de Parámetro propuestos. Los valores propuestos anulan la configuración actual, permitiendo a los usuarios con acceso de lectura invocar métodos de validación de componentes predefinidos con configuraciones alternativas. Las instalaciones de Apache NiFi que no implementan diferentes niveles de autorización para ver y modificar la configuración del Contexto de Parámetros no están sujetas a esta vulnerabilidad. La actualización a Apache NiFi 2.11.0 es la mitigación recomendada, que requiere acceso de escritura para enviar solicitudes de validación de Contexto de Parámetros.
