What this means

OS Command Injection in jscover affects jscover (npm). Severity is critical. jscover through 1.0.0 is vulnerable to Command Injection. It allows execution of arbitrary command via the source argument.

AI coding agents often install or upgrade packages automatically in npm. A critical vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
