Summary
CVE-2023-42441 affects Vyper, a Pythonic Smart Contract Language for the Ethereum Virtual Machine (EVM). Between versions 0.2.9 and 0.3.10, locks with empty string names `@nonreentrant("")` or `@nonreentrant(\'\')` did not trigger reentrancy checks at runtime. This vulnerability, now resolved in version 0.3.10, could potentially lead to security issues if a contract is not properly secured. To mitigate this risk, it is advised to ensure that the lock name is a non-empty string.
