If you cannot patch yet, users should consider applying input validation or output encoding workarounds if feasible. No vendor advisory content is currently available indicating that the issue is already mitigated or that no action is required.

Description

The authentication endpoint fails to encode user-supplied input before rendering it in the web page, allowing for script injection. An attacker can leverage this by injecting malicious scripts into the authentication endpoint. This can result in the user's browser being redirected to a malicious website, manipulation of the web page's user interface, or the retrieval of information from the browser. However, session hijacking is not possible due to the httpOnly flag protecting session-related cookies.
