CVE-2018-17215
An information-disclosure issue was discovered in Postman through 6.3.0.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.64%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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).
