AI-suggested

Upgrade the Simpler Checkout WordPress plugin to version 1.5.4 or later, where this vulnerability is fixed. Since the vulnerability is resolved in 1.5.4, applying this official fix is the recommended remediation.

Description

The Simpler Checkout WordPress plugin versions before 1.5.4 have a vulnerability where the plugin does not properly restrict order creation permissions and uses an automatic login link with a key that remains empty until the store owner completes plugin setup. This flaw allows subscriber-level users on stores that have not completed setup to log in as administrators.
