The WordPress File Sharing Plugin WordPress plugin before 2.0.5 does not check authorization before displaying files and folders, allowing users to gain access to those filed by manipulating IDs which can easily be brute forced

The WordPress File Sharing Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in versions up to, and including, 2.0.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
