CVE-2026-20127 exploitation installed KeyDrift on Cisco Catalyst SD-WAN systems

Cve
CVE-2026-20127 [1] [2]
Exploitation
UAT-11473 exploited the vulnerability to install the KeyDrift malware framework, which collected sensitive keying information and provided backdoor and command-and-control capabilities. [1]
Mitigation

Product
Cisco Catalyst SD-WAN Controller, Manager and Validator, including on-premises systems and Cisco-hosted cloud deployments [2]
Status
Historical exploitation identified; Cisco says it is aware of limited exploitation. [2]
