- Summary
- Vyper has incorrect re-entrancy lock when key is empty string
- Details
-
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. - Database specific
