DescriptionNVD

This affects the package portprocesses before 1.0.5. If (attacker-controlled) user input is given to the killProcess 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.

AnalysisAI

This affects the package portprocesses before 1.0.5. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available.

Technical ContextAI
