WP Fast Total Search < 1.69.234 - Missing Authorization

Description

The WP Fast Total Search plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on several functions like ajax_set_pause, ajax_se_style_preview, and WPFTS_jxResponse in versions up to, and including, 1.68.232. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify plugin settings.
