CVE-2021-46873

5.3 mediumEPSS 0.5%

Medium (5.3) in wireguard wireguard. EPSS 0.5% chance of exploitation in the next 30 days.

WireGuard, such as WireGuard 0.5.3 on Windows, does not fully account for the possibility that an adversary might be able to set a victim's system time to a future value, e.g., because unauthenticated NTP is used. This can lead to an outcome in which one static private key becomes permanently useless.
