Weakness in Transfer Validation Logic in @solana/pay
Description
Solana Pay is a protocol and set of reference implementations that enable developers to incorporate decentralized payments into their apps and services. When a Solana Pay transaction is located using a reference key, it may be checked to represent a transfer of the desired amount to the recipient, using the supplied validateTransfer function. An edge case regarding this mechanism could cause the validation logic to validate multiple transfers. This issue has been patched as of version 0.2.1. Users of the Solana Pay SDK should upgrade to it. There are no known workarounds for this issue.
