Detailed vulnerability description
The vulnerability allows a remote attacker to perform cross-site request forgery attacks.
The vulnerability exists due to insufficient validation of the HTTP request origin and lack of authorisation checks in the "bwpl_configure_slug()" function registered as an "admin_init" action. A remote attacker can change the plugin settings at "/wp-admin/options-permalink.php" and disable the protection.
This vulnerability leads to unauthorized option update via CSRF or unauthenticated usage of the "admin-ajax.php".
