我正在创建浏览器插件和 Package 我使用webpack。我有以下依赖关系，导致漏洞。

"devDependencies": {
    "babel-minify-webpack-plugin": "^0.3.1",
    "minify-html-webpack-plugin": "^0.0.5",
    "uglifyjs-webpack-plugin": "^2.2.0",
    "webpack": "^4.43.0",
    "webpack-cli": "^3.3.12",
    "webpack-webext-plugin": "github:rpl/webpack-webext-plugin"
},

当我输入npm i或npm audit时，会收到一条以

found 21 vulnerabilities (9 low, 8 moderate, 3 high, 1 critical)
run `npm audit fix` to fix them, or `npm audit` for details

npm audit fix无法修复这些漏洞。如何删除这些漏洞？
有人能解释一下这些漏洞是什么吗？如果我继续用这些漏洞构建我的项目会有什么危害？
