Improper Neutralization of Special Elements used in an OS Command.

moderate severity Published Mar 11, 2021

Package

npm react-dev-utils (npm)

Affected versions

>= 0.4.0, < 11.0.4

Patched versions

11.0.4

Description

react-dev-utils prior to v11.0.4 exposes a function, getProcessForPort, where an input argument is concatenated into a command string to be executed. This function is typically used from react-scripts (in Create React App projects), where the usage is safe. Only when this function is manually invoked with user-provided values (ie: by custom code) is there the potential for command injection. If you're consuming it from react-scripts then this issue does not affect you.
