20 Aug 2026, 9:35 PM	The Hacker News	3.0	Critical NetScaler Flaw Can Bypass Authentication on Certain Gateway and AAA Servers Citrix patched two NetScaler flaws, including CVE-2026-19490 (CVSS 9.3), an authentication bypass affecting customer-managed NetScaler ADC and Gateway appliances configured as SSL VPN, ICA Proxy, CVPN, RDP Proxy, or AAA virtual servers. The bypass has version-specific triggers—some versions require a SAML action to be configured, while earlier 14.1 and 13.1 builds are vulnerable regardless. A second flaw, CVE-2026-19489 (CVSS 8.8), is a memory overflow that only triggers when SIP ALG is enabled on an LSN group. Why: If your organization runs customer-managed NetScaler ADC or Gateway for VPN or AAA, check whether you are on a vulnerable build (pre-14.1-73.32 or pre-13.1-63.21) and patch immediately—authentication bypass on a VPN gateway is directly exploitable. Most SaaS founders and developers not running NetScaler can ignore this. security netscaler citrix vpn authentication-bypass
