Descriptions

In affected versions of WordPress, a password reset link emailed to a user does not expire upon changing the user password. Access would be needed to the email account of the user by a malicious party for successful execution. This has been patched in version 5.4.1, along with all the previously affected versions via a minor release (5.3.3, 5.2.6, 5.1.5, 5.0.9, 4.9.14, 4.8.13, 4.7.17, 4.6.18, 4.5.21, 4.4.22, 4.3.23, 4.2.27, 4.1.30, 4.0.30, 3.9.31, 3.8.33, 3.7.33).

En las versiones afectadas de WordPress, un enlace de restablecimiento de contraseña enviado por correo electrónico a un usuario no caduca tras cambiar la contraseña del usuario. Se necesitaría el acceso a la cuenta de correo electrónico del usuario por una parte maliciosa para una ejecución con éxito. Esto ha sido corregido en la versión 5.4.1, junto con todas las versiones afectadas anteriormente por medio de una versión menor (versiones 5.3.3, 5.2.6, 5.1.5, 5.0.9, 4.9.14, 4.8.13, 4.7.17, 4.6.18, 4.5.21, 4.4.22, 4.3.23, 4.2.27, 4.1.30, 4.0.30, 3.9.31, 3.8.33, 3.7.33).

Several vulnerabilities were discovered in Wordpress, a web blogging tool. They allowed remote attackers to perform various Cross-Side Scripting (XSS) and Cross-Site Request Forgery (CSRF) attacks, create files on the server, disclose private information, create open redirects, poison cache, and bypass authorization access and input sanitation.
