CVE-2026-16695

Local code execution via sample-script command injection

Published Aug 12, 2026 · Updated Aug 12, 2026

OS command injection in ACS 1.1.2.0 through 1.1.9.13 allows local attackers to execute arbitrary code on workstations. Sample scripts in Documentation/Sample_Scripts/Linux_Mac_Other pass crafted input parameters to operating-system commands without neutralizing special elements. Exploitation requires local access and application interaction, and injected commands run with the privileges of the process that launches ACS.
