Detailsinfo

A vulnerability was found in veronalabs WP Statistics Plugin up to 14.16.4 on WordPress and classified as critical. This issue affects the function check_ajax_referer of the component AJAX Handler.

The product does not perform an authorization check when an actor attempts to access a resource or perform an action. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The WP Statistics plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 14.16.4. This is due to missing capability checks on multiple AJAX handlers including `wp_statistics_get_filters`, `wp_statistics_getPrivacyStatus`, `wp_statistics_updatePrivacyStatus`, and `wp_statistics_dismiss_notices`. These endpoints only verify a `wp_rest` nonce via `check_ajax_referer()` but do not enforce any capability checks such as `current_user_can()` or the plugin's own `User::Access()` method. Since the `wp_rest` nonce is available to all authenticated WordPress users, this makes it possible for authenticated attackers, with Subscriber-level access and above, to access sensitive analytics data (user IDs, usernames, emails, visitor tracking data), retrieve and modify privacy audit compliance status, and dismiss administrative notices.

The weakness was released by Jack Pas. It is possible to read the advisory at wordfence.com. The identification of this vulnerability is CVE-2026-3488 since 03/03/2026.
