CVE-2023-42460
September 26, 2023
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.
