CVE-2019-18672
Insufficient checks in the finite state machine of the ShapeShift KeepKey hardware wallet before firmware 6.2.2 allow a partial reset of cryptographic secrets to known values via crafted messages.

This vulnerability can be exploited by unauthenticated attackers and the interface is reachable via WebUSB.
