CVE-2022-35917

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.

### Description When a Solana Pay transaction is located using a [reference key](https://github.com/solana-labs/solana-pay/blob/master/SPEC.md#reference), it may be checked to represent a transfer of the desired amount to the recipient, using the supplied [`validateTransfer` function](https://github.com/solana-labs/solana-pay/blob/master/core/src/validateTransfer.ts). An edge case regarding this mechanism could cause the validation logic to validate multiple transfers. ### Impact Most known Solana Pay point of sale applications are currently run on physical point of sale devices, which makes this issue unlikely to occur. However, there may be web-based point of sale applications using the protocol where it may be more likely to occur. ### Patches This issue has been patched as of version [`0.2.1`](https://www.npmjs.com/package/@solana/pay/v/0.2.1). Users of the Solana Pay SDK should upgrade to it.

Solana Pay es un protocolo y un conjunto de implementaciones de referencia que permiten a desarrolladores incorporar pagos descentralizados en sus aplicaciones y servicios. Cuando es localizada una transacción de Solana Pay usando una clave de referencia, puede comprobarse que representa una transferencia del importe deseado al destinatario, usando la función suministrada "validateTransfer". Un caso de borde en relación con este mecanismo podría causar a la lógica de comprobación, comprobar múltiples transferencias. Este problema ha sido corregido a partir de la versión "0.2.1". Los usuarios del SDK de Solana Pay deberían actualizarlo. No se presentan mitigaciones conocidas para este problema
