CVE-2026-20127, patched in February 2026, lets attackers add rogue peers and steal IPsec key material from controllers.
Lumen says exploited products included Versa, N-able, Cisco SD-WAN, VeloCloud and possibly Quest KACE; KeyDrift hit Cisco controllers.
Talos says UAT-11473 stole suspected IPsec keys from space, defense, and policy targets; patches shipped in February 2026.
UAT-11473 uses a CVSS 10.0 auth bypass on Cisco Catalyst SD-WAN to plant in-process key stealers; fixes exist but no workaround.
CVE-2026-76418, scored 8.6, lets unauthenticated attackers reload firewalls when SSL VPN uses secondary authentication.
CVE-2026-20127 (CVSS 10) gives unauthenticated admin access to SD-WAN controllers; KeyDrift malware siphoned keying material and Volt Typhoon kept exploiting the flaw after disclosure.
The malware hooks vdaemon to copy AES-256 key material; Cisco calls exploitation limited and lists fixed trains.
Talos says the implant lives in controller processes, steals data-plane keys, and overlaps Volt Typhoon infrastructure.
