XSS in hello.js
Quick fix
GHSA-7jh9-6cpf-h4m7 — hellojs: upgrade to the fixed version with the command below.
npm install hellojs@1.18.6Details
This affects the package hello.js before 1.18.6. The code get the param oauth_redirect from url and pass it to location.assign without any check and sanitisation. So we can simply pass some XSS payloads into the url param oauth_redirect, such as `javascript:alert(1)`.
