Input validation vulnerability in Sequential Order Numbers for WooCommerce 3.6.2

The plugin called “Sequential Order Numbers for WooCommerce” on WordPress has a security issue in all versions up to 3.6.2. This is because it does not properly check for a security code when performing a certain function. As a result, attackers who are not logged in can potentially trick a site administrator into taking an action, like clicking on a link, that they should not be able to do.
