CVE-2026-116215

MacCMS v10 through 2026.1000.4056 contains a race condition vulnerability in Card::useData() that allows authenticated members to redeem one recharge card multiple times via the user/buy endpoint. Attackers can send many concurrent flag=card requests that pass the non-locking card read before it is marked used, inflating user_points to buy VIP upgrades and paid content.
