CVE-2024-32647 vyper performs double eval of raw_args in create_from_blueprint

Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. In versions 0.3.10 and prior, using the createfromblueprint builtin can result in a double eval vulnerability when rawargs=True and the args argument has side-effects. It can be seen that the buildcreateIR function of t...
