Summary

The PickPlugins Product Designer for WooCommerce WordPress plugin through 1.0.40 does not perform any capability check and its nonce verification is inverted, accepting requests with an invalid or absent nonce while rejecting valid ones, and it does not validate the post the data is written to, allowing unauthenticated users to insert design template data into the metadata of any post on the site.
