It seems that axios v0.19.1 introduced a new bug. 

The bug comes from https://github.com/axios/axios/pull/2464

All urls containing `javascript`keyword is throwing XSS error.  So, all following urls cannot be used in axios any more:

- https://www.javascript.com
- https://stackoverflow.com/questions/tagged/javascript
- https://www.google.com/search?q=javascript

Here is a link to regexp: https://regexr.com/4rsst

Expected behavior: axios should accept `javascript` in urls
lib/helpers/isValidXss.js
'use strict';
module.exports = function isValidXss(requestURL) {
  var xssRegex = /(\b)(on\w+)=|javascript|(<\s*)(\/*)script/gi;
  return xssRegex.test(requestURL);
};
