ESLint 插件不会标记不安全的方法

我已经安装了 ESLint 以及一些安全插件来尝试进行一些 javascript 分析，但是当我向其输入少量易受攻击的 javascript 时，却没有得到任何输出。

我使用以下命令安装了 ESLint：

npm i -g eslint eslint-plugin-standard eslint-plugin-import \
eslint-plugin-node eslint-plugin-promise eslint-config-standard \
eslint-config-semistandard
npm i -g eslint-plugin-scanjs-rules
npm i -g eslint-plugin-angularjs-security-rules
npm i -g eslint-plugin-react
npm i -g eslint-plugin-security
npm i -g eslint-plugin-no-wildcard-postmessage
npm i -g eslint-plugin-no-unsanitized
npm i -g eslint-plugin-vue
npm i -g eslint-plugin-prototype-pollution-security-rules

然后我在两者上运行了 init：

npm init 
eslint --init
? How would you like to use ESLint? To check syntax and find problems
? What type of modules does your project use? JavaScript modules (import/export)
? Which framework does your project use? None of these
? Where does your code run? (Press <space> to select, <a> to toggle all, <i> to invert selection)Browser
? What format do you want your config file to be in? JavaScript

Successfully created .eslintrc.js file in /js-analysis

我输入了以下易受攻击的演示代码：

$ cat demo.js
var input = ['value',window.location.search.substring(2)]
document.getElementById("demo1").innerHTML = input.value;

var url = window.location.search.substring(1);
document.getElementById("demo2").innerHTML = "<a href='"+url+"'>About</a>";

该包如下所示：

$ cat package.json
{
  "name": "js-analysis",
  "version": "1.0.0",
  "description": "",
  "main": "demo.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}

但是这个命令（插件说应该标记易受攻击的 unnerHTML 使用）没有输出：

$ eslint --plugin no-unsanitized ./demo.js

我仍然不确定为什么 --plugin 选项不起作用，但是我发现的解决方法是将以下内容添加到运行“eslint --init”后创建的 .eslintrc.js 文件中。

通过手动添加插件及其规则，如下所示：

cat .eslintrc.js
module.exports = {
  "env" : {
    "browser" : true,
    "es6" : true /** all es6 features except modules */
  },
  "plugins" : [
    "scanjs-rules",
    "no-unsanitized",
    "prototype-pollution-security-rules"
  ],
  "rules" : {
    /** useful rules from eslint **/

    /** ScanJS rules **/
    "scanjs-rules/accidental_assignment": 1,
    "scanjs-rules/assign_to_hostname" : 1,
    "scanjs-rules/assign_to_href" : 1,
    "scanjs-rules/assign_to_location" : 1,
    "scanjs-rules/assign_to_onmessage" : 1,
    "scanjs-rules/assign_to_pathname" : 1,
    "scanjs-rules/assign_to_protocol" : 1,
    "scanjs-rules/assign_to_search" : 1,
    "scanjs-rules/assign_to_src" : 1,
    "scanjs-rules/call_Function" : 1,
    "scanjs-rules/call_addEventListener" : 1,
    "scanjs-rules/call_addEventListener_deviceproximity" : 1,
    "scanjs-rules/call_addEventListener_message" : 1,
    "scanjs-rules/call_connect" : 1,
    "scanjs-rules/call_eval" : 1,
    "scanjs-rules/call_execScript" : 1,
    "scanjs-rules/call_hide" : 1,
    "scanjs-rules/call_open_remote=true" : 1,
    "scanjs-rules/call_parseFromString" : 1,
    "scanjs-rules/call_setImmediate" : 1,
    "scanjs-rules/call_setInterval" : 1,
    "scanjs-rules/call_setTimeout" : 1,
    "scanjs-rules/identifier_indexedDB" : 1,
    "scanjs-rules/identifier_localStorage" : 1,
    "scanjs-rules/identifier_sessionStorage" : 1,
    "scanjs-rules/new_Function" : 1,
    "scanjs-rules/property_addIdleObserver" : 1,
    "scanjs-rules/property_createContextualFragment" : 1,
    "scanjs-rules/property_crypto": 1,
    "scanjs-rules/property_geolocation" : 1,
    "scanjs-rules/property_getUserMedia" : 1,
    "scanjs-rules/property_indexedDB" : 1,
    "scanjs-rules/property_localStorage" : 1,
    "scanjs-rules/property_mgmt" : 1,
    "scanjs-rules/property_sessionStorage" : 1,

    /** no-unsanitized rules**/
    "no-unsanitized/method": "error",
    "no-unsanitized/property": "error",

    /** prototype-pollution-security-rules rules**/
    "prototype-pollution-security-rules/detect-merge": 1,
    "prototype-pollution-security-rules/detect-merge-objects": 1,
    "prototype-pollution-security-rules/detect-merge-options": 1,
    "prototype-pollution-security-rules/detect-deep-extend": 1
  }
};

可以运行如下组合插件：

$ eslint vulnerable-javascript.js
