https://notcve.org/view.php?id=CVE-2021-39200
WordPress is a free and open-source content management system written in PHP and paired with a MySQL or MariaDB database. In affected versions output data of the function wp_die() can be leaked under certain conditions, which can include data like nonces. It can then be used to perform actions on your behalf. This has been patched in WordPress 5.8.1, along with any older affected versions via minor releases. 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') •

PHPMailer 6.1.8 through 6.4.0 allows object injection through Phar Deserialization via addAttachment with a UNC pathname. NOTE: this is similar to CVE-2018-19296, but arose because 6.1.8 fixed a functionality problem in which UNC pathnames were always considered unreadable by PHPMailer, even in safe contexts. As an unintended side effect, this fix eliminated the code that blocked addAttachment exploitation. PHPMailer versión 6.1.8 hasta la versión 6.4.0 permite la inyección de objetos a través de Phar Deserialization vía addAttachment con un nombre de ruta UNC. NOTA: esto es similar a CVE-2018-19296, pero surgió porque la versión 6.1.8 corrigió un problema de funcionalidad en el que los nombres de ruta UNC siempre se consideraban ilegibles por PHPMailer, incluso en contextos seguros. • https://github.com/PHPMailer/PHPMailer/commit/e2e07a355ee8ff36aba21d0242c5950c56e4c6f9 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3B5WDPGUFNPG4NAZ6G4BZX43BKLAVA5B https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KPU66INRFY5BQ3ESVPRUXJR4DXQAFJVT • CWE-502: Deserialization of Untrusted Data •
