Simple Staff List < 2.2.5 - Missing Authorization via ajax_flush_rewrite_rules and staff_member_export

Description

The Simple Staff List plugin for WordPress is vulnerable to unauthorized access of data and modification of data due to a missing capability check on the ajax_flush_rewrite_rules and staff_member_export functions in versions up to, and including, 2.2.4. This makes it possible for authenticated attackers, with subscriber-level access and above, to flush rewrite rules and export a list of staff members.
