Description

react-dev-utils on Windows allows developers to run a local webserver for accepting various commands, including a command to launch an editor. The input to that command was not properly sanitized, allowing an attacker who can make a network request to the server (either via CSRF or by direct request) to execute arbitrary commands on the targeted system. 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.

Affected configurations

• facebook react-dev-utils (>= 1.0.0 < 1.0.4) • facebook react-dev-utils (>= 2.0.0 < 2.0.2) • facebook react-dev-utils (>= 3.0.0 < 3.1.2) • facebook react-dev-utils (>= 4.0.0 < 4.2.2) • facebook react-dev-utils (>= 5.0.0 < 5.0.2)
