Citrix has patched two vulnerabilities in NetScaler ADC and NetScaler Gateway — a critical memory overread (CVE-2026-3055) that lets unauthenticated attackers leak session tokens from SAML IDP-configured appliances, and a high-severity race condition (CVE-2026-4368) that can expose one user’s authenticated session to another. Given the rapid exploitation history of prior NetScaler memory-read flaws, organizations running affected on-premises builds should prioritize patching immediately
