A remote code execution issue was discovered in the WooCommerce Products Filter (aka WOOF) plugin before 2.2.0 for WordPress, as demonstrated by the shortcode parameter in a woof_redraw_woof action. The plugin implemented a page redraw AJAX function accessible to anyone without any authentication. WordPress shortcode markup in the "shortcode" parameters would be evaluated. Normally unauthenticated users can't evaluate shortcodes as they are often sensitive.

A local file inclusion issue was discovered in the WooCommerce Products Filter (aka WOOF) plugin before 2.2.0 for WordPress, as demonstrated by the shortcode parameter in a woof_redraw_woof action. The vulnerability is due to the lack of args/input validation on render_html before allowing it to be called by extract(), a PHP built-in function. Because of this, the supplied args/input can be used to overwrite the $pagepath variable, which then could lead to a local file inclusion attack.
