Citrix Secure Access Client Flaw CVE-2026-118268 Allows Local SYSTEM Escalation; Fixed in 26.11.1.6
CVE-2026-118268 is a local privilege escalation vulnerability in the Citrix Secure Access Client for Windows that lets a standard user gain SYSTEM privileges. The defect is fixed in version 26.11.1.6 and later. Because the flaw affects endpoints rather than internet-facing services, internet search results such as ZoomEye's 0 application matches and 1 title match do not reliably indicate how many installations are exposed. Experts recommend assessing exposure through endpoint management inventory, checking installed versions, service states, and binaries, including on VDI images and devices that have not recently checked in. The remedy is upgrading endpoints, with follow-up steps like removing older binaries and rotating credentials if compromise is suspected.
