Unauthorized survey creation via missing nonce validation
Published Jan 24, 2026 · Updated Jan 24, 2026
Cross-site request forgery in Devsoft Baltic OÜ SurveyJS: Drag & Drop Form Builder 2.5.2 and earlier allows remote attackers to create surveys. The SurveyJS_AddSurvey AJAX handler accepts an administrator-session request and creates a survey without verifying a WordPress nonce. Exploitation requires an authenticated site administrator to open an attacker-controlled link or page; the demonstrated consequence is unauthorized survey creation.
