CVE-2026-10520 Ivanti Sentry OS Command Injection Vulnerability

Ivanti Sentry (formerly known as MobileIron Sentry) contains an OS command injection vulnerability which could allow a remote unauthenticated user to achieve root-level remote code execution. This vulnerability can be successfully exploited in cases where the Sentry appliance is in an unmanaged state with its endpoints externally reachable. The use of mTLS with EPMM or restricted HTTPS access through Neurons for MDM makes interfaces inaccessible to external actors.

From the CISA KEV catalogue version 2026.11.06, with Cybergen analysis. Updated 6 Nov 2026.
