Descriptions
In affected versions of WordPress, files with a specially crafted name when uploaded to the Media section can lead to script execution upon accessing the file. This requires an authenticated user with privileges to upload files. This has been patched in version 5.4.1, along with all the previously affected versions via a minor release (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).
En las versiones afectadas de WordPress, los archivos con un nombre especialmente diseñado cuando se cargan en la sección Multimedia pueden conllevar a una ejecución de script al acceder al archivo. Esto requiere un usuario autenticado con privilegios para cargar archivos. 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).
