Arbitrary code execution in kill-by-port

Quick fix

GHSA-mm4f-47ch-f7hx — kill-by-port: upgrade to the fixed version with the command below.

npm install kill-by-port@0.0.2

Details

This affects the package kill-by-port before 0.0.2. If (attacker-controlled) user input is given to the killByPort function, it is possible for an attacker to execute arbitrary commands. This is due to use of the child_process exec function without input sanitization.
