An issue in the billing and license activation subsystem allows remote attackers to bypass payment authorization workflows. By exploiting insufficient cryptographic validation or lack of server-side state verification on promotional/lifetime-deal (LTD) redemption codes, an unauthenticated attacker can forge valid redemption tokens or replay existing single-use codes to activate permanent, tier-highest paid subscriptions without a financial transaction.
