Technical summary

The Formidable Forms WordPress plugin, prior to version 6.32.1, does not properly validate the status of a PayPal subscription payment before marking it complete. This vulnerability allows unauthenticated users to bypass payment and trigger paid form actions, such as digital content access, license delivery, and membership activation, without being charged. The issue arises from the plugin's inadequate payment validation mechanism, which fails to verify the legitimacy of PayPal subscription payments. This could lead to unauthorized access to paid content or services, potentially affecting site administrators and users who rely on paid features.

Defensive priority

Medium-priority defensive review recommended due to potential for unauthorized form action triggering.

Recommended defensive actions

• Review and update Formidable Forms plugin to version 6.32.1 or later
• Verify payment validation for PayPal subscriptions
• Monitor for unauthorized form actions
• Implement compensating controls for digital content access and license delivery
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes

The Formidable Forms plugin for WordPress, version prior to 6.32.1, does not validate PayPal subscription payments properly. This oversight allows unauthenticated users to bypass payment and trigger paid form actions, potentially leading to unauthorized access to digital content or services. Evidence from the NVD and WPScan suggests that the plugin's payment validation mechanism is insufficient. Defenders should verify payment validation for PayPal subscriptions, review and update the plugin to version 6.32.1 or later, and monitor for unauthorized form actions. Additionally, implementing compensating controls for digital content access and license delivery can help mitigate potential impacts.
