Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.34%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
This affects the package killport before 1.0.2. If (attacker-controlled) user input is given, it is possible for an attacker to execute arbitrary commands. This is due to use of the child_process exec function without input sanitization. Running this PoC will cause the command touch success to be executed, leading to the creation of a file called success.
