Details

Vyper vulnerable to incorrect ordering of arguments for kwargs passed to internal calls ### Impact Internal calls to internal functions with more than 1 default argument are compiled incorrectly. Depending on the number of arguments provided in the call, the defaults are added not right-to-left, but left-to-right. If the types are incompatible, typechecking is bypassed. In the `bar()` function in the following code, `self.foo(13)` is compiled to `self.foo(13,12)` instead of `self.foo(13,1337)`. ```vyper @internal def foo(a:uint256 = 12, b:uint256 = 1337): pass @internal def bar(): self.foo(13) ``` note that at the time of publication, the ability to pass kwargs to internal functions is an undocumented feature that does not seem to be widely used. ### Patches patched in c3e68c302aa6e1429946473769dd1232145822ac ### Workarounds _Is there a way for users to fix or remediate the vulnerability without upgrading?_ ### References _Are there any links users can visit to find out more?_
