Input validation vulnerability in PlainInventory – Inventory Management Plugin 3.1.9

The PlainInventory plugin used for managing inventory in WordPress is at risk of a security issue called Cross-Site Request Forgery. This can happen in all versions up to 3.1.9 because the plugin does not properly check for a special code called a nonce. This can allow hackers who are not logged in to change settings and add harmful code to a website, as long as they can trick the website owner into taking an action, like clicking a link.
