CVSS: 9.8EPSS: 0%CPEs: 1EXPL: 1CVE-2021-44223 – WordPress Core < 5.8 - Dependency Confusion
https://notcve.org/view.php?id=CVE-2021-44223
WordPress before 5.8 lacks support for the Update URI plugin header. This makes it easier for remote attackers to execute arbitrary code via a supply-chain attack against WordPress installations that use any plugin for which the slug satisfies the naming constraints of the WordPress.org Plugin Directory but is not yet present in that directory. WordPress versiones anteriores a 5.8, carece de soporte para el encabezado del plugin Update URI. Esto facilita a atacantes remotos una ejecución de código arbitrario por medio de un ataque a la cadena de suministro contra instalaciones de WordPress que usen cualquier plugin cuyo slug satisfaga las restricciones de nomenclatura del directorio de plugins de WordPress.org pero que aún no esté presente en dicho directorio • https://make.wordpress.org/core/2021/06/29/introducing-update-uri-plugin-header-in-wordpress-5-8 https://vavkamil.cz/2021/11/25/wordpress-plugin-confusion-update-can-get-you-pwned • CWE-345: Insufficient Verification of Data Authenticity •

It's strongly recommended that you keep auto-updates enabled to receive the fix. • https://github.com/WordPress/wordpress-develop/security/advisories/GHSA-m9hc-7v5q-x8q5 https://hackerone.com/reports/1142140 https://www.debian.org/security/2021/dsa-4985 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 7.6EPSS: 0%CPEs: 3EXPL: 0CVE-2021-39201 – Authenticated cross-site scripting (XSS) in WordPress editor
https://notcve.org/view.php?id=CVE-2021-39201
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) 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. • https://github.com/WordPress/wordpress-develop/security/advisories/GHSA-wh69-25hr-h94v https://hackerone.com/reports/1142140 https://www.debian.org/security/2021/dsa-4985 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
