How to fix?

Upgrade vyper to version 0.3.8 or higher.

Overview

vyper is a Pythonic Smart Contract Language for the EVM.

Affected versions of this package are vulnerable to Function Call With Incorrect Order of Arguments when processing default keyword arguments for internal calls, which are added from left to right rather than from right to left. If the types are incompatible typechecking is bypassed.

NOTE: The ability to pass kwargs to internal functions is an undocumented feature.
