This is due to the plugin's sanitization function `sec_check_post_fields()` only running on the `save_post` hook, while WordPress allows custom fields to be added via the `wp_ajax_add_meta` AJAX endpoint without triggering `save_post`. The `ce_filter()` function then outputs these unsanitized meta values directly into page content without escaping. 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 plugin Code Embed para WordPress es vulnerable a cross-site scripting almacenado a trav\u00e9s de valores meta de campos personalizados en todas las versiones hasta la 2.5.1, inclusive.
