Update, patch or deactivate.
Update WP Promoter to a release after 1.3, or disable and remove it until a fixed version is available.

Technical description
The WP Promoter plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the reset_stats() function in versions up to, and including, 1.3. The function is hooked to both the wp_ajax_wpp-reset_stats and wp_ajax_nopriv_wpp-reset_stats actions and contains no authentication, authorization, or nonce validation. This makes it possible for unauthenticated attackers to reset the plugin's bar and popup statistics by deleting the wpp_bar and wpp_popup options.
