What happens

A regular expression denial of service (ReDoS) flaw was found in Function interpolateName in interpolateName.js in webpack loader-utils via the resourcePath variable in interpolateName.js. A badly or maliciously formed string could be used to send crafted requests that cause a system to crash or take a disproportional amount of time to process. This issue has been patched in versions 1.4.2, 2.0.4 and 3.2.1.
