### Summary 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. ### Details The `build_IR` function of the `RawLog` class fails to properly unwrap the variables provided as topics. Consequently, incorrect values are logged as topics. ### PoC ```vyper x: bytes32 @external def f(): self.x = 0x1234567890123456789012345678901234567890123456789012345678901234 raw_log([self.x], b"") # LOG1(offset:0x60, size:0x00, topic1:0x00) y: bytes32 = 0x1234567890123456789012345678901234567890123456789012345678901234 raw_log([y], b"") # LOG1(offset:0x80, size:0x00, topic1:0x40) ``` ### Patches Fixed in https://github.com/vyperlang/vyper/pull/3977. ### Impact Incorrect values can be logged which may result in unexpected behavior in client-side applications relying on these logs.
