CVE-2024-32645: vyper performs incorrect topic logging in raw_log

April 25, 2024 (updated January 21, 2025)

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. In particular, no uses of raw_log() were found at all in production; it is apparently not a well-known function.
