CVE-2026-84756Network attack vectorHinoki check available

Subscriber privilege escalation via legacy Stripe IPN

Published Sep 3, 2026 · Updated Sep 3, 2026

Incorrect privilege assignment in WC Lovers WCFM Membership 2.11.11 and earlier allows remote authenticated users to elevate privileges. Legacy Stripe IPN handlers accept a membership action that overwrites a user's role without enforcing the Subscriber's authorization boundary. A Subscriber account and network access to those handlers are required; the published materials do not specify the highest obtainable role.
