Descriptions

In WordPress before 4.7.3, there is authenticated Cross-Site Scripting (XSS) via Media File Metadata. This is demonstrated by both (1) mishandling of the playlist shortcode in the wp_playlist_shortcode function in wp-includes/media.php and (2) mishandling of meta information in the renderTracks function in wp-includes/js/mediaelement/wp-playlist.js.

En WordPress en versiones anteriores a 4.7.3, hay XSS autenticada a través de Media File Metadata. Esto es demostrado tanto por (1) mal manejo de la playlist shortcode en la función wp_playlist_shortcode en wp-includes/media.php y (2) mal manejo de de meta información en la función renderTracks en wp-includes/js/mediaelement/wp-playlist.js.
