The PHP to Page plugin for WordPress is vulnerable Local File Inclusion to Remote Code Execution in versions up to, and including, 0.3 via the 'php-to-page' shortcode. This allows authenticated attackers with subscriber-level permissions or above, to include local file and potentially execute code on the server. While subscribers may need to poison log files or otherwise get a file installed in order to achieve remote code execution, author and above users can upload files by default and achieve remote code execution easily.
The product makes files or directories accessible to unauthorized actors, even though they should not be.
