The recent discovery of CVE-2025-13139 reveals a critical vulnerability in the SurveyJS Drag & Drop WordPress Form Builder plugin. This flaw allows attackers to exploit Cross-Site Request Forgery (CSRF), enabling unauthorized survey creation. As system administrators and hosting providers, understanding this threat is vital for protecting your servers and user data.
This vulnerability affects all versions of the SurveyJS plugin up to and including 1.12.20. The root cause is a lack of nonce validation on the SurveyJS_AddSurvey AJAX action. Without proper validation, attackers can generate surveys by tricking an authenticated user, such as an admin, into making a malicious request.
For hosting providers and system administrators, this vulnerability underscores the importance of robust server security practices. A successful exploit can compromise sensitive information and tarnish your organization's reputation. Additionally, it can lead to further attacks, including brute-force attacks and potential malware deployment on your servers.
Ensure that all plugins, including SurveyJS, are regularly updated to the latest versions. This measure often includes security patches that can resolve known vulnerabilities.
A web application firewall (WAF) can help protect against CSRF attacks by filtering out malicious traffic before it reaches your server.
Install monitoring tools to track any unusual survey creation activities or other irregular behaviors on your server. This proactive approach can help detect threats early.
