URL Redirection to Untrusted Site ('Open Redirect')
An Open Redirect vulnerability for all browsers in Jupyter Notebook and some browsers (Chrome, Firefox) in JupyterHub allows crafted links to the login page, which will redirect to a malicious site after successful login. Servers running on a base_url prefix are not affected.
CWE-601 - Open Redirect
An open redirect attack employs a URL parameter, HTML refresh tags, or a DOM based location change to exploit the trust of a vulnerable domain to direct the users to a malicious website. The attack could lead to higher severity vulnerabilities such as unauthorized access control, account takeover, XSS, and more.
