Crypto < 2.19 - Authentication Bypass via log_in

Description

The plugin for WordPress is vulnerable to authentication bypass due a to limited arbitrary method call to 'crypto_connect_ajax_process::log_in' function in the 'crypto_connect_ajax_process' function. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the username.
