CVE-2026-15150Network attack vector

Unauthenticated currency credit via unverified payment receiver

Published Aug 21, 2026 · Updated Aug 21, 2026

Payment bypass in myCred before 3.2.5 allows remote attackers to credit arbitrary amounts of in-site currency via payment notifications. The buyCRED PayPal IPN path validates the payment amount but does not compare the notification's receiver with the configured merchant account. No authentication or user interaction is required; payment to an attacker-controlled gateway account produces the currency credit.
