Vyper has incorrect re-entrancy lock when key is empty string

Published Sep 18, 2023 · Updated Sep 24, 2024 · Assigned by GitHub_M

Description

Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine (EVM). Starting in version 0.2.9 and prior to version 0.3.10, locks of the type `@nonreentrant("")` or `@nonreentrant('')` do not produce reentrancy checks at runtime. This issue is fixed in version 0.3.10. As a workaround, ensure the lock name is a non-empty string.
