## Technical details

The vulnerability is a stored XSS in the multi_media field renderer, which outputs user-supplied data into href attributes, hidden input values, and HTML elements without proper escaping, while neighboring attributes use esc_attr(). Combined with a permissions bypass in Redux_Extension_Users::user_meta_save() that validates against a 'checkuser_id' from the request body rather than the current user, a Subscriber can write fields declared for 'manage_options'. Exploitation requires a theme or plugin registering a multi_media field via the Redux Users API, and stored scripts execute when an administrator views the attacker's profile.
