Severity ?
3.7 (Low) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N

Summary
Vyper is a Pythonic Smart Contract Language for the EVM. There is an error in the stack management when compiling the `IR` for `sha3_64`. Concretely, the `height` variable is miscalculated. The vulnerability can't be triggered without writing the `IR` by hand (that is, it cannot be triggered from regular vyper code). `sha3_64` is used for retrieval in mappings. No flow that would cache the `key` was found so the issue shouldn't be possible to trigger when compiling the compiler-generated `IR`. This issue isn't triggered during normal compilation of vyper code so the impact is low. At the time of publication there is no patch available.

         value: "Vyper es un lenguaje de contrato inteligente pitónico para EVM. Hay un error en la gestión de la pila al compilar el `IR` para `sha3_64`. En concreto, la variable \"altura\" está mal calculada. La vulnerabilidad no se puede activar sin escribir el `IR` a mano (es decir, no se puede activar desde un código vyper normal). `sha3_64` se utiliza para la recuperación en asignaciones. No se encontró ningún flujo que almacenara en caché la \"clave\", por lo que no debería ser posible desencadenar el problema al compilar el \"IR\" generado por el compilador. Este problema no se activa durante la compilación normal del código vyper, por lo que el impacto es bajo. Al momento de publicación no hay ningún parche disponible.",
