This bypasses the restrictions imposed on users who do not have the permission to post `unfiltered_html`. ### Patches This has been patched in WordPress 5.8, and will be pushed to older versions via minor releases (automatic updates). It's strongly recommended that you keep auto-updates enabled to receive the fix. ### References https://wordpress.org/news/category/releases/ https://hackerone.com/reports/1142140 ### For more information If you have any questions or comments about this advisory: * Open an issue in [HackerOne](https://hackerone.com/wordpress)"},{"lang":"es","value":"WordPress es un sistema de administración de contenidos gratuito y de código abierto escrito en PHP y emparejado con una base de datos MySQL o MariaDB. ### Impacto: El problema permite a un usuario autenticado pero pocos privilegiados (como un colaborador/autor) ejecutar un ataque de tipo XSS en el editor. Esto omite las restricciones impuestas a usuarios que no presentan permiso para publicar \"unfiltered_html\". ### Parche: Esto ha sido parcheado en WordPress versión 5.8, y será empujado a versiones anteriores por medio de versiones menores (actualizaciones automáticas). Se recomienda encarecidamente que mantenga habilitadas las actualizaciones automáticas para recibir la corrección. ### Referencias: https://wordpress.org/news/category/releases/ https://hackerone.com/reports/1142140 ### Para más información.
