WP Statistics Authorization and XSS Flaws

Stored Cross-Site Scripting in WP Statistics plugin (≤14.16.4) allows unauthenticated attackers to inject malicious JavaScript into admin dashboard analytics pages. The vulnerability stems from unsafe handling of utm_source URL parameters that persist into database-backed charts, executing when administrators view Referrals Overview or Social Media pages. With CVSS 7.2 and network vector requiring no authentication, this represents elevated risk for WordPress sites using this analytics plugin, though no active exploitation confirmed at time of analysis.

WP Statistics plugin for WordPress versions up to 14.16.4 fail to enforce capability checks on multiple AJAX endpoints, allowing authenticated Subscriber-level users to access sensitive analytics data, retrieve and modify privacy audit status, and dismiss administrative notices. The vulnerability stems from reliance on nonce verification alone without role-based access control, affecting all installations with the plugin active and at least one authenticated user account. No public exploit code or active exploitation has been confirmed at time of analysis.
