Descriptions

In affected versions of WordPress, authenticated users with upload permissions (like authors) are able to inject JavaScript into some media file attachment pages in a certain way. This can lead to script execution in the context of a higher privileged user when the file is viewed by them. This has been patched in version 5.4.2, along with all the previously affected versions via a minor release (5.3.4, 5.2.7, 5.1.6, 5.0.10, 4.9.15, 4.8.14, 4.7.18, 4.6.19, 4.5.22, 4.4.23, 4.3.24, 4.2.28, 4.1.31, 4.0.31, 3.9.32, 3.8.34, 3.7.34).

En las versiones afectadas de WordPress, los usuarios autenticados con permisos de carga (como los autores) pueden inyectar JavaScript en algunas páginas de archivos adjuntos multimedia de determinada manera. Esto puede conllevar a una ejecución de script en el contexto de un usuario con mayores privilegios cuando el archivo es visualizado por ellos. Esto ha sido parcheado en la versión 5.4.2, junto con todas las versiones afectadas anteriormente por medio de una versión menor (versiones 5.3.4, 5.2.7, 5.1.6, 5.0.10, 4.9.15, 4.8.14, 4.7.18, 4.6.19, 4.5.22, 4.4.23, 4.3.24, 4.2.28, 4.1.31, 4.0.31, 3.9.32, 3.8.34, 3.7.34)
