Inactive plan enrollment via unchecked checkout parameter
Published Apr 15, 2026 · Updated Apr 15, 2026
Missing authorization in ProfilePress 4.16.12 and earlier allows remote authenticated users to subscribe to inactive membership plans. The process_checkout function accepts an attacker-controlled change_plan_sub_id value without enforcing the selected plan's active status. Subscriber-level access is sufficient to create the otherwise disallowed subscription, altering membership entitlements without administrative approval.
