Estado: ModificadaMedia (5.4)—

En las versiones afectadas de WordPress, puede ser diseñada una carga útil especial que puede conllevar a que los scripts sean ejecutados dentro del bloque de búsqueda del editor de bloques. Esto requiere un usuario autenticado con la capacidad de agregar contenido. Esto ha sido corregido en la versión 5.4.1, junto con todas las versiones afectadas anteriormente por medio de una versión menor (versiones 5.3.3, 5.2.6, 5.1.5, 5.0.9, 4.9.14, 4.8.13, 4.7.17, 4.6.18, 4.5.21, 4.4.22, 4.3.23, 4.2.27, 4.1.30, 4.0.30, 3.9.31, 3.8.33, 3.7.33).
