Description
WordPress Plugin WP eCommerce is prone to a security bypass vulnerability. Exploiting this issue may allow attackers to perform otherwise restricted actions and subsequently dump all client personal information (including names, emails, addresses, etc?) or buy products and change the status of their transaction to Accepted Payment without actually making the payment. WordPress Plugin WP eCommerce version 3.8.14.3 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 3.8.14.4 or latest
