En versiones anteriores a 4.1.30, 4.2.26 y 4.3.12, el AbstractItemNormalizer del serializador no valida el tipo de recurso devuelto al resolver IRIs de relaci\u00f3n, permitiendo una confusi\u00f3n de tipos donde un recurso de un tipo no intencionado puede ser asignado silenciosamente a una propiedad de relaci\u00f3n. Un atacante que puede enviar solicitudes de escritura (POST/PUT/PATCH) a un endpoint de API Platform con relaciones escribibles puede proporcionar un IRI de relaci\u00f3n apuntando a un recurso de un tipo diferente al de la clase declarada de la relaci\u00f3n. Debido a que getResourceFromIri() no pasa una $operation a IriConverter::getResourceFromIri(), la guarda de tipo is_a en IriConverter.php:86 es omitida. Para propiedades de relaci\u00f3n sin tipo (estilo heredado solo @var), el objeto de tipo incorrecto es asignado silenciosamente, corrompiendo invariantes y potencialmente alimentando l\u00f3gica posterior que asume el tipo declarado (CWE-843). Para propiedades tipadas (PHP 8.x moderno), la sustituci\u00f3n es bloqueada por el PropertyAccessor de Symfony con una InvalidTypeException.
