Cisco SD-WAN 0-day exploited with no patch available (CVE-2026-20245)

Attackers are exploiting a privilege escalation 0-day in Cisco Catalyst SD-WAN Manager that can lead to arbitrary command execution as root. Cisco says exploitation requires netadmin privileges or chaining from CVE-2026-20182/CVE-2026-20127, and it has observed limited in-the-wild activity while a fix is still pending. Organizations should urgently restrict admin access, monitor for anomalous netadmin actions, and apply Cisco’s interim mitigations.
