CVE-2012-4379

Estado: ModificadaMedia (6.5)—

MediaWiki, en versiones anteriores a la 1.18.5 y versiones 1.19.x anteriores a la 1.19.2, no envía una cabecera HTTP X-Frame-Options restrictiva, lo que permite que atacantes remotos lleven a cabo ataques de secuestro de clic mediante una respuesta API embebida en un elemento IFRAME.
