Summary
_abi_decode input not validated in complex expressions in Vyper
Details

Vyper is a Pythonic Smart Contract Language for the EVM. The _abi_decode() function does not validate input when it is nested in an expression. Uses of _abi_decode() can be constructed which allow for bounds checking to be bypassed resulting in incorrect results. This issue has not yet been fixed, but a fix is expected in release 0.3.10. Users are advised to reference pull request #3626.
