Membership payment bypass via unchecked subscription ownership
Published Apr 4, 2026 · Updated Apr 4, 2026
Missing authorization in ProfilePress 4.16.11 and earlier allows remote authenticated users to obtain paid lifetime plans without payment. The process_checkout() function trusts change_plan_sub_id without verifying that the referenced active subscription belongs to the checkout user, then applies its proration to the new plan. Subscriber-level access, another user's active subscription, and a paid lifetime-plan checkout are required; the consequence is a payment bypass and unauthorized membership access.
