CVE-2018-20149

Estado: ModificadaMedia (5.4)—

En WordPress, en versiones anteriores a la 4.9.9 y versiones 5.x anteriores a la 5.0.1, cuando se emplea el servidor HTTP de Apache, los autores podrían subir archivos arbitrarios que omiten las restricciones de tipo MIME planeadas, lo que conduce a Cross-Site Scripting (XSS). Esto queda demostrado por un archivo .jpg sin datos JPEG.
