Description

WordPress 5.7 < 5.7.1 / 5.6 < 5.6.3 / 5.5 < 5.5.4 / 5.4 < 5.4.5 / 5.3 < 5.3.7 / 5.2 < 5.2.10 / 5.1 < 5.1.9 / 5.0 < 5.0.12 / 4.9 < 4.9.17 / 4.8 < 4.8.16 / 4.7 < 4.7.20 is affected by multiple vulnerabilities:

 - A user with the ability to upload files (like an Author) can exploit an XML parsing issue in the Media Library leading to XXE attacks. This requires WordPress installation to be using PHP 8. Access to internal files is possible in a successful XXE attack. (CVE-2021-29447)

 - One of the blocks in the WordPress editor can be exploited in a way that exposes password-protected posts and pages. This requires at least contributor privileges. (CVE-2021-29450)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to WordPress version 5.7.1, 5.6.3, 5.5.4, 5.4.5, 5.3.7, 5.2.10, 5.1.9, 5.0.12, 4.9.17, 4.8.16, 4.7.10, or later.
