Lifecycle Timeline
2DescriptionCVE.org
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.
AnalysisAI
User enumeration via authorization bypass in the Wallet for WooCommerce WordPress plugin (versions up to and including 1.6.4) allows any authenticated subscriber-level user to extract login names, email addresses, and user IDs for every WordPress account on the site, including administrators. The flaw exists because the plugin exposes a 'search-user' nonce - required to call its AJAX search handler - directly in the wallet_param JavaScript object rendered on the publicly accessible WooCommerce My Account page, making it trivially obtainable by any logged-in user. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated WordPress session with subscriber-level access or higher on the target site - a role typically obtained via free self-registration if open registration is enabled (WordPress default for many WooCommerce stores). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) accurately frames the risk profile: network-accessible, low complexity, but gated behind subscriber-level authentication and producing only a confidentiality impact limited to user account metadata. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a free subscriber account on a WordPress site running Wallet for WooCommerce ≤1.6.4, logs in, and loads the WooCommerce My Account page, where the plugin's wallet_param JavaScript object exposes the 'search-user' nonce in the page source. The attacker then issues POST requests to wp-admin/admin-ajax.php with that nonce, iterating through search terms (single letters, common name prefixes) to enumerate all WordPress usernames, email addresses, and user IDs, including those of site administrators. … |
| Remediation | Update the Wallet for WooCommerce plugin to the first version released after changeset 3585829 on the WordPress plugin repository; the exact patched version number is not independently confirmed in the available advisory data, so administrators should verify the current version in the WordPress plugin directory against the changelog. … Detailed patch versions, workarounds, and compensating controls in full report. |
