vyper performs incorrect topic logging in raw_log

CVE-2024-32645

Description

Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. In versions 0.3.10 and prior, incorrect values can be logged when raw_log builtin is called with memory or storage arguments to be used as topics. A contract search was performed and no vulnerable contracts were found in production. The build_IR function of the RawLog class fails to properly unwrap the variables provided as topics. Consequently, incorrect values are logged as topics. As of time of publication, no fixed version is available.
