Citrix has released emergency patches for CVE-2026-88779, a high-severity zero-day vulnerability in NetScaler ADC and Gateway that is being actively exploited in attacks targeting specific organizations. The flaw allows attackers to cause denial-of-service conditions and potentially execute arbitrary code. Security teams are urged to apply the updates immediately and check systems for signs of compromise.
Why now: Actively exploited zero-days in widely used enterprise infrastructure like NetScaler prompt urgent patching and incident-response concerns.
