CVE-2025-36640

Local privilege escalation via tray app servicing

Published Jan 13, 2026 · Updated Jan 13, 2026

Local privilege escalation in Tenable Agent before 10.9.3 and 11.0.0 through 11.0.2 allows local users to gain elevated privileges. The flaw occurs during installation or removal of the Windows Agent Tray App, but Tenable has not published the vulnerable operation or input handling. A low-privileged Windows user must reach the affected servicing workflow; successful exploitation grants access beyond the user's original security context.
