At a glance
CVE-2025-12903 is a high-severity Authorization Bypass Through User-Controlled Key vulnerability in the Payment Plugins Braintree For WooCommerce WordPress plugin, affecting versions <= 3.2.78. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 3.2.79; sites on affected versions should update now. Disclosed November 2025, reported by type5afe.
Vulnerability Overview
The Payment Plugins Braintree For WooCommerce plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the wc-braintree/v1/3ds/vaulted_nonce REST API endpoint in all versions up to, and including, 3.2.78. This is due to the endpoint being registered with permission_callback set to __return_true and processing user-supplied token IDs without verifying ownership or authentication. This makes it possible for unauthenticated attackers to retrieve payment method nonces for any stored payment token in the system, which can be used to create fraudulent transactions, charge customer credit cards, or attach payment methods to other subscriptions.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality.
CWE-639: Authorization Bypass Through User-Controlled Key
Reaching this weakness in Payment Plugins Braintree For WooCommerce <= 3.2.78 takes a caller who can reach the endpoint. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.
Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For Payment Plugins Braintree For WooCommerce the fix is 3.2.79: builds <= 3.2.78 are affected, anything from 3.2.79 onward is not.
Remediation
Update to version 3.2.79, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Payment Plugins Braintree For WooCommerce 3.2.79 closes this, and updating the plugin is the step that ends it.
