CISA adds CVE-2026-88771 and CVE-2026-88772 to KEV amid confirmed global NetScaler exploitation

Active exploitation of two critical NetScaler flaws forces immediate patching despite operational friction. Evidence trail confirms global reach but lacks actor attribution. Default DTLS settings and slow firmware cycles amplify exposure across critical infrastructure.

Organizations must isolate appliances, preserve VPX images, rotate KEKs and certificates, then rebuild. Next reporting threshold is 15 October 2026 when CISA is expected to publish aggregated compromise counts from federal sensors.

⚡ Prediction

CISA: 40% of federal NetScaler instances remain unpatched past 15 October 2026, triggering mandatory incident reporting.
