This upgrade of css-loader to version 1.0.0 is a major breaking change and is not compatible with the version of Webpack used in this project. This will break the build.

Incompatibility Details:

  • This project uses webpack: "^1.13.1".
  • css-loader@1.0.0 requires webpack: "^4.0.0" as a peer dependency.

Problem:
Merging this PR will cause the build to fail due to this incompatibility. The webpack configuration files (webpack.config.js, webpack.prod.config.js) also use a syntax for loaders that is deprecated and incompatible with newer Webpack versions.

Recommended Actions:
This automated PR should be closed. To address the Prototype Pollution vulnerability (SNYK-JS-JSYAML-13961110), one of the following approaches should be taken in a new PR:

  1. Webpack Migration (Recommended for long-term health):

    • Upgrade Webpack to version 4 or 5.
    • Upgrade all related Webpack loaders and plugins (e.g., extract-text-webpack-plugin is deprecated and should be replaced with mini-css-extract-plugin for Webpack 4+).
    • Update the Webpack configuration files to the new syntax.

  2. Targeted Patch (Short-term fix):

    • Since the project uses an older version of npm (3.10.3) that doesn't support overrides, you can use npm shrinkwrap to force the transitive dependency js-yaml to a patched version (e.g., 3.13.1 or higher). This involves generating and manually editing an npm-shrinkwrap.json file.
