{"id":"CVE-2021-46873","details":"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.","modified":"2026-07-09T03:25:22.471758Z","published":"2023-01-29T23:15:08.703Z","references":[{"type":"ADVISORY","url":"https://lists.zx2c4.com/pipermail/wireguard/2021-August/006916.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wireguard/wireguard-windows","events":[{"introduced":"28e903804aa1302b791c24093dd7f42f0c7d0952"},{"last_affected":"28e903804aa1302b791c24093dd7f42f0c7d0952"}],"database_specific":{"cpe":"cpe:2.3:a:wireguard:wireguard:0.5.3:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0.5.3"},{"last_affected":"0.5.3"}],"source":"CPE_STRING"}}],"versions":["0.5.3","v0.5.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-46873.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}
