Hi there.
The warnings are around the inclusion of jquery-ui version 1.12.1 by the plugin.
In the free version it’s in lib/main.default.js : line 11 – the version is set to 1.12.1
In the pro version it’s in plugins/wp-file-manager-pro/file_folder_manager_pro.php : line 968
Versions of jquery older than 1.13.2 are vulnerable to a cross site scripting attack. Here’s the CVE https://www.cvedetails.com/cve/CVE-2022-31160/
