Paid Member Subscriptions < 2.10.5 - Cross-Site Request Forgery via ajax_add_log_entry

Description The Paid Member Subscriptions plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.10.4. This is due to missing or incorrect nonce validation on the ajax_add_log_entry function. This makes it possible for unauthenticated attackers to modify log entries via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
