CVE-2021-46873
Last modified
CVE-2021-46873 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. 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.. EPSS estimates a 0.47% chance of exploitation in the next 30 days.
