CVE-2025-10684 is a vulnerability identified in the Construction Light WordPress theme prior to version 1.6.8. The issue stems from improper authentication (CWE-287) and lack of Cross-Site Request Forgery (CSRF) protection (CWE-352) on an AJAX action used to activate certain theme features. Specifically, the theme does not verify that the user initiating the AJAX request has sufficient privileges, nor does it validate the request's origin via CSRF tokens. As a result, any authenticated user, including those with minimal privileges such as subscribers, can trigger this AJAX action to activate arbitrary functionalities or settings within the theme. This can lead to unauthorized changes to the website's configuration or behavior, undermining the integrity of the site. The vulnerability has a CVSS v3.1 base score of 4.3, indicating medium severity. The attack vector is network-based (remote), requires low attack complexity, and requires the attacker to have some level of privileges (authenticated user). No user interaction is necessary beyond authentication. The scope is unchanged, meaning the vulnerability affects only the theme and not the entire WordPress installation or other components. No known exploits have been reported in the wild as of the publication date. The vulnerability was reserved in September 2025 and published in December 2025. No official patch links are provided yet, indicating that users should monitor for updates from the theme developer or WPScan advisories. This vulnerability highlights the importance of proper authorization and CSRF protections in WordPress themes, especially for AJAX endpoints that can modify site behavior.

For European organizations using the Construction Light WordPress theme, this vulnerability poses a risk of unauthorized modification of website features by low-privileged users. Although it does not directly compromise confidentiality or availability, the integrity of the website can be affected, potentially leading to unauthorized content changes, activation of unwanted features, or configuration alterations that could facilitate further attacks. This could damage organizational reputation, reduce user trust, and potentially lead to compliance issues if website integrity is critical. Small and medium enterprises (SMEs) and organizations relying on WordPress for their public-facing websites are particularly at risk. Since the vulnerability requires authenticated access, organizations with weak user management or many low-privileged users are more vulnerable. The lack of known exploits suggests limited immediate threat, but the medium severity score and ease of exploitation by authenticated users warrant prompt attention. The impact is more pronounced in sectors where website integrity is crucial, such as e-commerce, government services, and media.

1. Immediately update the Construction Light WordPress theme to version 1.6.8 or later once the patch is released by the developer. 2. Until a patch is available, restrict the number of users with authenticated access, especially limiting subscriber or low-privilege accounts. 3. Implement additional access controls at the WordPress level to prevent low-privileged users from accessing AJAX endpoints related to theme activation. 4. Use security plugins that can monitor and block suspicious AJAX requests or enforce CSRF protections. 5. Conduct regular audits of user roles and permissions to ensure minimal necessary privileges are assigned. 6. Monitor website logs for unusual AJAX activity that could indicate exploitation attempts. 7. Educate administrators and users about the risks of unauthorized access and the importance of strong authentication practices. 8. Consider deploying a Web Application Firewall (WAF) with custom rules to detect and block unauthorized AJAX activation attempts. 9. Follow WPScan and theme developer advisories for updates and additional security recommendations.
