Overview

Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF). The /login and /change endpoints can return the authenticated user's authentication token in response to a GET request. Since GET requests aren't protected with a CSRF token, this could lead to a malicious 3rd party site acquiring the authentication token.
