Description

A flaw was found in webpack-dev-server. When the development server operates over plain HTTP, a remote attacker can exploit a cross-origin source code exposure vulnerability. This allows a malicious website, visited by a developer, to load the bundled application source code as a script and read it across origins. Consequently, this could lead to the disclosure of sensitive application source code.
