## Technical details

The vulnerability is a stored cross-site scripting (XSS) flaw in the Redux_Multi_Media component, where array keys in the 'multi_media' field are not sanitized during save but are rendered directly into HTML id attributes without escaping. While wp_kses_post sanitizes leaf values, array keys bypass this sanitization entirely, enabling attribute breakout attacks that inject arbitrary JavaScript code.
