Affected packages
• npm hellojs: < 1.18.6 → fixed in 1.18.6
Description
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)`.
