Summary		(es) Plunk es una plataforma de correo electrónico de código abierto construida sobre AWS SES. Antes de la 0.7.0, existía una vulnerabilidad de falsificación de petición del lado del servidor (SSRF) en el gestor de webhook de SNS. Un atacante no autenticado podría enviar una petición manipulada que causaba que el servidor realizara una petición HTTP GET saliente arbitraria a cualquier host accesible desde el servidor. Esta vulnerabilidad está corregida en la 0.7.0.
