Overview

vyper is a Pythonic Smart Contract Language for the EVM.

Affected versions of this package are vulnerable to Improper Check for Unusual or Exceptional Conditions due to the incorrect handling of value= keyword arguments in the raw_call function when delegatecall or staticcall are used. An attacker can mislead developers into believing that funds are being transferred with the call when, in fact, no value is sent.
