WP Statistics < 14.16.5 - Subscriber+ Sensitive Information Exposure and Privacy Audit Manipulation

Description

The plugin is vulnerable to Missing Authorization 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.
