CVE-2023-41052

Vyper CVE-2023-41052 affects the Pythonic smart contract language Vyper. In affected versions, the evaluation order of arguments to builtins uint256_addmod, uint256_mulmod, ecadd, and ecmul does not follow source order, which can cause side effects in one argument to be relied upon by others. The...
