Technical description
The Block Bad Bots and Stop Bad Bots Crawlers and Spiders and Anti Spam Protection plugin for WordPress is vulnerable to unauthorized access of data due to an insufficient capability check on the 'stopbadbots_check_wordpress_logged_in_cookie' function in all versions up to, and including, 11.58.
