Descriptions

A Regular expression denial of service (ReDoS) flaw was found in Function interpolateName in interpolateName.js in webpack loader-utils 2.0.0 via the url variable in interpolateName.js.

Se ha encontrado un fallo de denegación de servicio de expresión Regular (ReDoS) en la función interpolateName en el archivo interpolateName.js en webpack loader-utils 2.0.0 por medio de la variable url en interpolateName.js

A flaw was found in loader-utils webpack library. When the url variable from interpolateName is set, the prototype can be polluted. This issue could lead to a regular expression Denial of Service (ReDoS), affecting the availability of the affected component.

The package loader-utils before 1.4.2, from 2.0.0 and before 2.0.4 as well as versions from 3.0.0 but below 3.2.1 are vulnerable to Regular Expression Denial of Service (ReDoS) via the resourcePath variable due to insecure usage of regular expressions. Some WordPress plugins and themes use this dependency, however, are not vulnerable to exploitation.
