Technical description
The Library File Manager WordPress plugin before 5.2.3 is using an outdated version of the elFinder library, which is know to be affected by security issues (CVE-2021-32682), and does not have any authorisation as well as CSRF checks in its connector AJAX action, allowing any authenticated users, such as subscriber to call it.
