What is CVE-2026-54608?

In versions 3.5.4-aurora and earlier of MythicalDash, a flaw in the payment processing mechanism allows authenticated users to manipulate the system. When a payment is initiated through Stripe, the backend endpoint creates a pending payment record prior to confirming the transaction. Without proper session validation or ownership checks, users can submit a payment code from an abandoned or failed transaction to the system. This behavior enables unauthorized virtual currency credits to be added to user accounts without actual payment confirmation, potentially leading to financial losses and abuse of hosting resources.

Affected Version(s)

MythicalDash <= 3.5.4-aurora
