CVE-2026-97652 in WP Statistics Plugin
Summary
by MITRE • 10/02/2026
The WP Statistics – Simple, privacy-friendly Google Analytics alternative plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via REQUEST_URI Query-Parameter Key in all versions up to, and including, 14.16.14 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The vulnerability identified within the WP Statistics plugin, specifically affecting versions up through 14.16.14, represents a significant security risk due to its nature as a Reflected Cross-Site Scripting flaw. This type of vulnerability arises from insufficient input sanitization and output escaping mechanisms when processing data derived from HTTP requests. The specific vector for this attack is the REQUEST_URI query parameter key, which allows unauthenticated attackers to inject arbitrary web scripts into pages served by the WordPress site. Because WP Statistics serves as a privacy-friendly alternative to Google Analytics, it handles substantial amounts of traffic data, making any compromise in its processing logic particularly dangerous for both website administrators and their end users who rely on accurate analytics reporting without compromising user privacy or security.
From a technical perspective, the core issue lies in how the application processes incoming request URIs before rendering them back to the client browser. When an attacker crafts a malicious URL containing script payloads within the REQUEST_URI parameter, the server fails to properly validate or escape these inputs prior to inclusion in the HTML response. Consequently, when a victim user clicks on such a link, their browser interprets the injected code as part of the page content and executes it. This execution occurs within the context of the vulnerable website, granting the attacker potential access to session cookies, authentication tokens, or other sensitive data stored locally by the browser for that domain. The lack of proper encoding ensures that special characters are not neutralized, allowing script tags and event handlers to function as intended rather than being treated as plain text.
The operational impact of this vulnerability extends beyond simple defacement or minor annoyances. Attackers can leverage Reflected Cross-Site Scripting to perform session hijacking, where they steal active user sessions to impersonate legitimate users, including administrators with elevated privileges. This could lead to unauthorized changes in site configuration, insertion of malicious plugins, or complete takeover of the WordPress installation. Furthermore, attackers may redirect victims to phishing sites designed to harvest credentials for other services if those credentials are reused across platforms. In environments where WP Statistics is used extensively, the high volume of traffic increases the likelihood that a victim will encounter such a crafted link, thereby amplifying the potential scale and frequency of successful attacks against site visitors.
Industry standards classify this flaw under CWE-79, which denotes Improper Neutralization of Input During Web Page Generation commonly known as Cross-site Scripting. The attack technique aligns with MITRE ATT&CK tactic T1059, specifically subcategory 007 for Command and Scripting Interpreter: JavaScript, as it involves executing client-side scripts to achieve malicious objectives such as data exfiltration or session manipulation. Understanding these classifications helps security professionals contextualize the severity and required remediation steps within broader organizational risk management frameworks.
To mitigate this vulnerability, immediate action is recommended by updating the WP Statistics plugin to a version newer than 14.16.14 where the input sanitization and output escaping issues have been addressed. Developers should ensure that all user-supplied data, particularly those originating from URL parameters like REQUEST_URI, are strictly validated against expected formats and encoded appropriately before being rendered in HTML contexts. Implementing Content Security Policy headers can also provide an additional layer of defense by restricting the sources from which scripts can be loaded or executed, thereby reducing the impact even if a script injection attempt occurs. Regular security audits and penetration testing focused on input validation practices are essential to prevent similar vulnerabilities from emerging in future updates or related plugins within the WordPress ecosystem.
