If an attacker can control the port, which in itself is a very sensitive value, they can inject arbitrary OS commands due to the usage of the exec function in a third-party module kill-port < 1.3.2.

Affected: npm: kill-port

Versions of `kill-port` prior to 1.3.2 are vulnerable to Command Injection. The package does not validate user input on the `kill` function. This may allow attackers to run arbitrary commands in the system if user input (such as the port number) is passed directly to the function.

## Recommendation

Upgrade to version 1.3.2 or later.
