Employee Directory <= 1.2.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'form_title' Shortcode Attribute

The Employee Directory plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'form_title' parameter in the `search_employee_directory` shortcode in all versions up to, and including, 1.2.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
