      "value": "A Server-Side Template Injection (SSTI) vulnerability was identified \nin the mail template functionality of the Axway SecureTransport product in version 5.5-20260326. This \nflaw \nallows an attacker with admin privileges to inject arbitrary Java code expressions, which are \nexecuted server-side when the template is rendered (i.e., during email \nsending). Successful exploitation of this flaw allows an attacker to \nexecute \narbitrary code on the server that results in full host compromise.\n\n\n\nThis issue affects all Axway SecureTransport versions prior 5.5-20260528 update."

      "value": "Una vulnerabilidad de inyección de plantillas del lado del servidor (SSTI) fue identificada en la funcionalidad de plantillas de correo del producto Axway SecureTransport en la versión 5.5-20260326. Esta falla permite a un atacante con privilegios de administrador inyectar expresiones de código Java arbitrarias, las cuales son ejecutadas del lado del servidor cuando la plantilla es renderizada (es decir, durante el envío de correo electrónico). La explotación exitosa de esta falla permite a un atacante ejecutar código arbitrario en el servidor, lo que resulta en el compromiso total del host.\n\nEste problema afecta a todas las versiones de Axway SecureTransport anteriores a la actualización 5.5-20260528."
