Recommendation: Plan a near-term fix — a public PoC already exists.

The WPForms WordPress plugin before 1.10.0.5 does not verify the authenticity of incoming PayPal webhook events before processing them, allowing unauthenticated attackers to forge webhook payloads and manipulate the payment state of arbitrary transactions.
