Overview
Affected versions of this package are vulnerable to Untrusted Search Path through the macOS host detector command execution in HostDetector.cs. An attacker can execute arbitrary code in the application's security context by supplying a malicious ioreg binary earlier in PATH and triggering the host.id resource detection on macOS. This affects applications that run the detector with a user-influenced search path, allowing local privilege escalation or code execution when the process launches the command by bare name.
