The Advanced File Manager — Ultimate WordPress File Manager and Document Library Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 5.2.14 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Subscriber-level access and above, and granted permissions by an Administrator, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
