CVE-2018-17215 Information

Description

An information-disclosure issue was discovered in Postman through 6.3.0. It validates a server’s X.509 certificate and presents an error if the certificate is not valid. Unfortunately the associated HTTPS request data is sent anyway. Only the response is not displayed. Thus all contained information of the HTTPS request is disclosed to a man-in-the-middle attacker (for example user credentials).
