Advisory

Source description from Wordfence Intelligence, credited to Krzysztof Zając.

The 10Web Booster – Website speed optimization, Cache & Page Speed optimizer plugin for WordPress is vulnerable to unauthorized loss of data due to insufficient validation on the option value being supplied to the two_init_flow_score and the two_init_flow_score functions hooked via nopriv AJAX in all versions up to, and including, 2.24.14. This makes it possible for unauthenticated attackers to delete arbitrary option values from the site.
