The remote keyless system on Honda Civic 2018 vehicles sends the same RF signal for each door-open request, which allows for a replay attack, a related issue to CVE-2019-20626.
A capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes).
