      "value": "Lemur manages TLS certificate creation. Prior to 1.9.3, CertificateExport placed its CertificatePermission ownership check inside the plugin.requires_key branch for POST /api/1/certificates//export. A plugin declaring requires_key false bypassed that check, and the handler still passed cert.private_key as an argument and recorded a key_view audit event. The bundled JavaTruststoreExportPlugin ignored the key, so the immediate exposure was limited to public certificate material and misleading audit entries, but a future plugin could have consumed the supplied key. The fix passes no private key to plugins that do not require one and confines ownership checks and key_view logging to actual private-key exports. This issue is fixed in version 1.9.3."

      "value": "Lemur gestiona la creación de certificados TLS. Antes de la versión 1.9.3, CertificateExport colocaba su verificación de propiedad de CertificatePermission dentro de la rama plugin.requires_key para POST /api/1/certificates//export. Un plugin que declaraba requires_key como falso eludía esa verificación, y el gestor aún pasaba cert.private_key como argumento y registraba un evento de auditoría key_view. El JavaTruststoreExportPlugin incluido ignoraba la clave, por lo que la exposición inmediata se limitaba a material de certificado público y entradas de auditoría engañosas, pero un plugin futuro podría haber consumido la clave suministrada. La solución no pasa ninguna clave privada a los plugins que no la requieren y confina las verificaciones de propiedad y el registro de key_view a las exportaciones reales de claves privadas. Este problema está solucionado en la versión 1.9.3."
