This is due to insufficient input sanitization on meta registration and missing output escaping in the `astra_get_responsive_background_obj()` function for four CSS-context sub-properties (`background-color`, `background-image`, `overlay-color`, `overlay-gradient`). This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page."},{"lang":"es","value":"El tema Astra para WordPress es vulnerable a Cross-Site Scripting Almacenado a través de los campos de metadatos de publicación 'ast-page-background-meta' y 'ast-content-background-meta' en todas las versiones hasta la 4.12.3, inclusive.
