Packages

Ecosystem	Package	Affected	Fixed in
npm	kill-by-port	< 0.0.2	0.0.2

Details

As written in the advisory (Markdown source, shown as plain text).

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.
