See original GitHub issue

Version: v7.1.1

Crash occured when # kun%ea%ba%5a%ba is parsed by queryString.parse This hash is valid and should be parsed correctly as { ' kun%ea%ba%5a%ba': null } For example in chrome’s development tools’ console the url https://google.com# kun%ea%ba%5a%ba can be parsed without problems:

const url = new URL("https://google.com#  kun%ea%ba%5a%ba");
url

Code to reproduce

const queryString = require('query-string');

const parsed = queryString.parse("#  kun%ea%ba%5a%ba");
console.log(parsed);
