Critical Cisco Nexus 9000 RCE Flaw (CVSS 9.8) — PoC Public
- Engineer — Act: Public PoC on GitHub for an unauthenticated root RCE on widely deployed data-center switches raises exploitation risk even with low EPSS; apply Cisco’s Nexus 9000 patch now and separately assess IOS XR exposure for the two 9.8-rated CVEs that have no available workaround.
- SOC/IR — Plan: No active exploitation confirmed yet, but the public PoC means attempts are likely imminent; build detections for anomalous access to Nexus 9000 management interfaces and prepare a hunt query baseline now before KEV listing forces a reactive response.
- Leader — Plan: Unauthenticated root RCE on core network switches with a public PoC is a meaningful risk-register item; confirm your network team has the Nexus 9000 patch cycle scheduled and note the IOS XR exposure for environments running that platform.
- Signals: CVE-2026-20212 — CISA KEV: not listed, EPSS 0.01, public PoC on GitHub
