Description
The Authentication Endpoint accepts user-supplied input without sufficient encoding, allowing for the injection of malicious JavaScript payloads. This vulnerability can be triggered by submitting crafted input to the Authentication Endpoint. Successful exploitation allows an attacker to redirect the user's browser to a malicious website, modify the web page's user interface, or extract sensitive information from the browser. However, due to the `httpOnly` flag on session-related cookies, session hijacking is not possible.
