CVE-2026-19127Network attack vectorHinoki check available

Paid subscription activation via unverified lifetime codes

Published Aug 6, 2026 · Updated Aug 6, 2026

Business-logic flaw in Postiz before 2.21.10 allows remote authenticated users to activate permanent paid subscriptions using forged codes. The POST /billing/lifetime route passes an organization identifier and attacker-supplied code to lifetimeDeal without adequately verifying code authenticity or single-use state. A valid Postiz account and configured Stripe integration are required; successful exploitation grants the highest lifetime tier without payment.
