What is CVE-2025-13384?

CVE-2025-13384 is a high-severity missing authorization vulnerability in codepeople CP Contact Form with PayPal, published on 22 Nov 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

The CP Contact Form with PayPal plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.3.56. This is due to the plugin exposing an unauthenticated IPN-like endpoint (via the 'cp_contactformpp_ipncheck' query parameter) that processes payment confirmations without any authentication, nonce verification, or PayPal IPN signature validation. This makes it possible for unauthenticated attackers to mark form submissions as paid without making actual payments by sending forged payment notification requests with arbitrary POST data (payment_status, txn_id, payer_email).

Weakness: CWE-862
