Name of the Vulnerable Software and Affected Versions CP Contact Form with PayPal plugin for WordPress versions through 1.3.56

Description The CP Contact Form with PayPal plugin for WordPress is susceptible to unauthorized payment confirmation. The plugin exposes an unauthenticated endpoint via the cp contactformpp ipncheck query parameter that processes payment confirmations without authentication, nonce verification, or PayPal IPN signature validation. This allows attackers to falsely mark form submissions as paid by sending forged payment notification requests with arbitrary POST data, including payment status, txn id, and payer email.

Recommendations Update the CP Contact Form with PayPal plugin to a version later than 1.3.56.
