Unauthorized participant changes via skipped CSRF validation
Published Nov 1, 2023 · Updated Feb 27, 2025
CSRF in PKP Web Application Library before 3.3.0-16 allows remote attackers to alter stage participants through a victim's browser. AddParticipantForm overrides validate() without calling the parent implementation, bypassing the form's CSRF token validation before processing participant changes. Exploitation requires an authenticated user to submit an attacker-controlled request, and the demonstrated consequence is an unauthorized participant change rather than data disclosure or service interruption.
