Description

CVE-2026-114031 is a local privilege escalation vulnerability in Illumio Core VEN for Windows. It arises from incorrect permission assignments in the VEN installer, which grants the LOCAL SERVICE account full access to critical VEN data and installation folders. Because the SYSTEM-privileged illumio-ven-ctl component reads and trusts these files, an attacker with NT AUTHORITY\LOCAL SERVICE privileges can modify the VEN configuration to execute arbitrary commands as SYSTEM.
