Staff data disclosure via unchecked appointment ownership
Published Mar 13, 2026 · Updated Mar 13, 2026
IDOR in N Squared Digital Simply Schedule Appointments 1.6.9.29 and earlier allows remote authenticated users to read appointment records. The get_item_permissions_check method accepts any user with ssa_manage_appointments but does not verify that the requested appointment belongs to that staff member. A Team Member or another custom-role user with that capability can supply another staff member's appointment ID and read customer personally identifiable information.
