この例では,css-select内のnth-checkで脆弱性が見つかったといわれています.

対処法

npm-force-resolutionsのインストール

$ npm -g install npm-force-resolutions -D

package.jsonの編集

package.jsonにresolutionを追加します.
中身には脆弱性のあったパッケージを追加します.

package.json
"resolutions": {
    "nth-check": "^2.0.1"
}

npm-force-resolutionsで強制的にバージョンを上げる

$ npx npm-force-resolutions

node_moduleを再インストール

$ rm -rf node_module
$ yarn install 
    or 
$ npm ci

脆弱性の再確認

$ npm audit 
    or
$ yarn audit
                                                                                
                       === npm audit security report ===
