  - WordPress is a free and open-source content management system written in PHP and paired with a MySQL or     MariaDB database. ### Impact The issue allows an authenticated but low-privileged user (like     contributor/author) to execute XSS in the editor. 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) (CVE-2021-39201)
