- GHSA-3hg2-r75x-g69m
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.
