## Affected

- Unknown Advanced File Manager: from 5.4.13, fixed in 6.0.0

## 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.

## What to do
