      "value": "An unintended cleartext issue exists in Go before 1.8.4 and 1.9.x before 1.9.1. RFC 4954 requires that, during SMTP, the PLAIN auth scheme must only be used on network connections secured with TLS. The original implementation of smtp.PlainAuth in Go 1.0 enforced this requirement, and it was documented to do so. In 2013, upstream issue #5184, this was changed so that the server may decide whether PLAIN is acceptable. The result is that if you set up a man-in-the-middle SMTP server that doesn't advertise STARTTLS and does advertise that PLAIN auth is OK, the smtp.PlainAuth implementation sends the username and password."

      "value": "Existe un problema de texto en claro no planeado en la versi\u00f3n 1.8.4 y versiones 1.9.x anteriores a la 1.9.4 de Go. La RFC 4954 requiere que durante la autenticaci\u00f3n SMTP, el esquema de autenticaci\u00f3n PLAIN solo se use en conexiones de red protegidas con TLS. La implementaci\u00f3n original de smtp.PlainAuth en Go 1.0 aseguraba el cumplimiento de este requisito y se document\u00f3 que esto se llevase a cabo. En 2013, problema upstream #5184, esto se modific\u00f3 para que el servidor pudiera decidir si se acepta PLAIN. El resultado es que si un usuario crea un servidor SMTP Man-in-the-Middle (MitM) que no anuncia STARTTLS pero s\u00ed anuncia que la autenticaci\u00f3n PLAIN es OK, la implementaci\u00f3n smtp.PlainAuth env\u00eda el nombre de usuario y contrase\u00f1a."
