Wallet for WooCommerce <= 1.6.4 - Missing Authorization to Authenticated (Subscriber+) User/Email Enumeration via terawallet_export_user_search AJAX Action
The Wallet for WooCommerce plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.6.4. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to enumerate the login name, email address, and user ID of all WordPress accounts — including administrators — by submitting arbitrary search terms to the AJAX handler. The required 'search-user' nonce is localized into the wallet_param object on the standard WooCommerce My Account page, which is accessible to any authenticated user, making it trivially obtainable by a Subscriber.
Quick answer
Wallet for WooCommerce should be reviewed and updated if it matches the affected versions. The recommended fix is to apply the vendor-supported patched version or the mitigation steps below, then retest the public website with Fixnx.

How to fix it
Wallet for WooCommerce is affected by CVE-2026-12103, a authorization bypass issue in versions up to 1.6.4. Wordfence lists the official remediation as updating to version 1.6.5, or a newer patched version. Prioritize internet-facing WordPress sites, sites with public registration, customer portals, WooCommerce checkout/account flows, Elementor/page-builder surfaces, and admin workflows where the vulnerable feature is enabled. If immediate patching is not possible, disable the affected plugin or feature, restrict access, and monitor for exploitation until the update is installed.
- Inventory every WordPress site that has Wallet for WooCommerce installed, including production, staging, multisite, client, and WooCommerce environments.
- Confirm the installed Wallet for WooCommerce version and compare it with the affected range from the Wordfence advisory.
- Update Wallet for WooCommerce to version 1.6.5, or to a newer vendor-supported patched version from the official WordPress update channel.
- If the update cannot be applied immediately, disable Wallet for WooCommerce or the affected feature and restrict access with roles, authentication, WAF rules, or temporary route blocking.
- Review affected REST endpoints, AJAX actions, roles, capabilities, account changes, orders, bookings, payments, and admin actions for unauthorized activity.
- Rotate administrator sessions, API keys, webhook secrets, payment or integration tokens, and affected credentials if logs or content review suggest compromise.
- Clear WordPress, object, CDN, page-builder, security plugin, and browser caches after patching so vulnerable assets or stored payloads are not served.

Verify the fix
- Confirm the running Wallet for WooCommerce version is version 1.6.5 or newer, and record the patched version in the remediation ticket.
- Verify unauthenticated or low-privilege users can no longer trigger the affected action, endpoint, account, payment, booking, or settings change.
- Review web server, WordPress, security plugin, WAF, database, and application logs for exploitation attempts before and after the fix.
- Retest normal visitor, subscriber, customer, editor, administrator, checkout, form, API, booking, or integration workflows to confirm expected behavior still works.
- Run a fresh Fixnx scan and document the public exposure state, patched version, log review, and any cleanup evidence.
