Descriptions

The wp_ajax_update_plugin function in wp-admin/includes/ajax-actions.php in WordPress before 4.6 makes a get_plugin_data call before checking the update_plugins capability, which allows remote authenticated users to bypass intended read-access restrictions via the plugin parameter to wp-admin/admin-ajax.php, a related issue to CVE-2016-6896.

La función wp_ajax_update_plugin en wp-admin/includes/ajax-actions.php en WordPress en versiones anteriores a 4.6 hace una llamada get_plugin_data antes de comprobar la capacidad update_plugins, lo que permite a usuarios remotos autenticados eludir las restricciones de acceso de lectura a través del parámetro plugin a wp-admin/admin-ajax.php, un caso relacionado con CVE-2016-6896.
