CVE-2026-2630Network attack vector

Authenticated code execution via OS command injection

Published Feb 17, 2026 · Updated Feb 17, 2026

OS command injection in Tenable Security Center 6.7.2 and earlier allows remote authenticated users to execute arbitrary code on its Linux host. Tenable identifies improper neutralization of OS command elements but has not disclosed the affected component, input, or command-building operation. Access to a valid application account and network reachability are required; successful exploitation compromises the hosted server.
