Inappropriate implementation in ChromeVox in Google Chrome OS prior to 62.0.3202.74 allowed a remote attacker in a privileged network position to observe or tamper with certain cleartext HTTP requests by leveraging that position.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.42%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
