CVE-2026-10520
Ivanti Sentry OS Command Injection Vulnerability
Ivanti · Sentry
Published July 21, 2026
What happened
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.
