Qubely <= 1.7.8 - Missing Authorization

The Qubely plugin for WordPress contains a missing authorization weakness that makes it possible for subscriber-level users to update the plugin's settings in versions up to, and including 1.7.8. This is due to missing capability checks on the ajax_update_qubely_options() function called via the wp_ajax_update_qubely_options AJAX action that makes it callable via any authenticated user.
