CVE-2026-4650 | FundPress <= 2.0.8 - Missing Authorization to Unauthenticated Arbitrary Donation Status Modification via donate_action_status AJAX Handler

The FundPress – WordPress Donation Plugin for WordPress is vulnerable to authorization bypass in versions up to and including 2.0.8. This is due to missing authorization and nonce verification in the donate_action_status() AJAX handler, which is registered to be accessible to unauthenticated users via wp_ajax_nopriv. The function only validates that the schema parameter equals 'donate-ajax' and that the required POST parameters are present, but fails to verify user capabilities, nonce tokens, or donation ownership. This makes it possible for unauthenticated attackers to modify the status of any donation by providing its ID (which are sequential integers and easily enumerable), allowing them to mark donations as completed, pending, cancelled, or any arbitrary status, potentially triggering email notifications and related side effects.
