Visitor deletion via missing CSRF nonce
Published Nov 21, 2022 · Updated Apr 30, 2025
Cross-site request forgery in Event Monster before 1.2.0 allows remote attackers to delete arbitrary visitor records via a forged administrator request. The visitor-management deleteallvisitor action accepts a POST containing an attendee ID without validating a WordPress CSRF nonce, so a crafted external form can invoke deletion in an administrator's authenticated session. Exploitation requires the administrator to be logged in and induced to submit the forged request; the demonstrated impact is integrity loss of visitor data, not confidentiality or service interruption.
