Description
The WP User Manager plugin for WordPress is vulnerable to a protection mechanism bypass of the "Prevent site access to visitors" feature in all versions up to, and including, 2.10.0. This is due to the site-lock check skipping enforcement whenever a request contains the 'wp-submit' and 'log' POST parameters, regardless of the requested URL. This makes it possible for unauthenticated attackers to view pages and content that the site owner restricted to logged-in users by POSTing those login form field names to them, on sites where the site access restriction is enabled.
