Descriptions

The register_routes function in wp-includes/rest-api/endpoints/class-wp-rest-posts-controller.php in the REST API in WordPress 4.7.x before 4.7.2 does not require an integer identifier, which allows remote attackers to modify arbitrary pages via a request for wp-json/wp/v2/posts followed by a numeric value and a non-numeric value, as demonstrated by the wp-json/wp/v2/posts/123?id=123helloworld URI.

La función register_routes en wp-includes/rest-api/endpoints/class-wp-rest-posts-controller.php en la API REST en WordPress 4.7.x en versiones anteriores a 4.7.2 no requiere un identificador de número entero, lo que permite a atacantes remotos modificar páginas arbitrarias a través de una solicitud para wp-json/wp/v2/posts seguida por un valor numérico y un valor no numérico, según lo demostrado mediante la URI wp-json/wp/v2/posts/123?id=123helloworld.
