AI-suggested
Until an official fix is available, users should consider disabling the PayPal Commerce webhook integration or implementing additional verification controls to ensure webhook authenticity. Monitor vendor channels for updates and apply patches once released.
Description
WPForms plugin for WordPress versions up to and including 1.10.0.1 has a vulnerability due to insufficient verification of PayPal webhook data authenticity. The plugin processes PayPal webhook JSON payloads without verifying the HMAC-SHA256 signature, allowing unauthenticated attackers who know a valid PayPal subscription_id to forge webhook events. This can lead to unauthorized modification of subscription payment records, such as reactivating cancelled or suspended subscriptions.
