Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.76%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
