Description
The Advanced File Manager WordPress plugin before 6.0.0 does not correctly determine whether a stored file is an SVG before sanitising it, allowing users granted file-manager access by an administrator to store a file containing script that is not stripped and that runs in the browser of anyone who opens it, including an administrator.
