The Advanced AJAX Page Loader plugin for WordPress is vulnerable to Cross-Site Request Forgery to Arbitrary File Upload in versions up to, and including, 2.7.7. This is due to missing nonce validation in the 'admin_init_AAPL' function and missing file type validation in the 'AAPL_options_validate' function.
