CVE-2018-6342 Information

Description

react-dev-utils on Windows allows developers to run a local webserver for accepting various commands including a command to launch an editor.

This issue affects multiple branches: 1.x.x prior to 1.0.4 2.x.x prior to 2.0.2 3.x.x prior to 3.1.2 4.x.x prior to 4.2.2 and 5.x.x prior to 5.0.2.
