      "value": "Lemur manages TLS certificate creation. Prior to 1.9.3, GET /api/1/destinations and GET /api/1/destinations/ relied only on authentication while sibling write handlers required admin_permission. DestinationOutputSchema returned raw options and copied them into pluginOptions without redacting sensitive values. The sftp-destination plugin stored password and privateKeyPass values in plaintext, allowing even a read-only user to retrieve credentials for remote certificate-deployment hosts. The exposed credentials could permit direct access to SFTP systems and TLS material outside the Lemur security boundary. The fix requires administrator permission for destination reads and redacts options marked sensitive. This issue is fixed in version 1.9.3."

      "value": "Lemur gestiona la creación de certificados TLS. Antes de 1.9.3, GET /api/1/destinations y GET /api/1/destinations/ dependían solo de la autenticación, mientras que los manejadores de escritura hermanos requerían permiso de administrador. DestinationOutputSchema devolvía opciones sin procesar y las copiaba en pluginOptions sin redactar valores sensibles. El plugin sftp-destination almacenaba los valores de password y privateKeyPass en texto plano, permitiendo incluso a un usuario de solo lectura recuperar credenciales para hosts remotos de despliegue de certificados. Las credenciales expuestas podrían permitir acceso directo a sistemas SFTP y material TLS fuera del límite de seguridad de Lemur. La solución requiere permiso de administrador para las lecturas de destino y redacta las opciones marcadas como sensibles. Este problema está solucionado en la versión 1.9.3."
