CVE-2026-4650 Details
Description
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.
A vulnerability allowing authorization bypass has been identified in the FundPress WordPress Donation Plugin, affecting versions through 2.0.8. The issue arises from inadequate authorization and nonce verification in the 'donate_action_status' AJAX handler, which is accessible to unauthenticated users. The handler only checks for the presence of certain POST parameters and that the schema parameter is set to 'donate-ajax', but it does not validate user capabilities or donation ownership. This flaw enables unauthenticated attackers to manipulate the status of any donation by sending its ID, which is a sequential integer and easily guessable. Attackers can change donation statuses to completed, pending, or cancelled, potentially triggering email notifications and other related effects.
Users are advised to update to FundPress version 2.0.9 or later, where this vulnerability has been addressed.
