CVE-2026-88774 · Severity: info · Published 2026-09-27

Citrix NetScaler ADC and Gateway are application delivery controllers that protect and optimize enterprise network traffic. A policy bypass vulnerability allows attackers to circumvent feature policies through improper HTTP URL expression handling, potentially bypassing intended security controls. The impact is limited to policy enforcement weakening rather than direct data exposure or system compromise.
