File Sharing & Download Manager < 2.1.7 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'fldr_ttl' Parameter

Description

The File Sharing & Download Manager – User Private Files plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'fldr_ttl' parameter in all versions up to, and including, 2.1.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
