User data access via retained post-logout sessions
Published Mar 25, 2022 · Updated Jul 9, 2026
Insufficient session expiration in SurveyKing 0.2.0 allows remote attackers to access user data with a session cookie retained after logout. The logout handler redirects to the login page without deleting the server-side session, leaving the prior cookie authorized for data requests. Exploitation requires access to a logged-out user's cached cookie and exposes data available to that user's session.
