- 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 release0.3.10. Users are advised to reference pull request #3626. - Database specific
