{"id":"CVE-2024-32645","aliases":["GHSA-xchq-w5r3-4wg3","PYSEC-2024-206"],"url":"https://o3.security/vulnerability/CVE-2024-32645","summary":"vyper performs incorrect topic logging in raw_log","details":"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.","published":"2024-04-25T17:18:27.026Z","modified":"2026-07-15T01:49:20.066924706Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"vyper","fixedVersion":"0.4.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/32xxx/CVE-2024-32645.json"},{"type":"ADVISORY","url":"https://github.com/vyperlang/vyper/security/advisories/GHSA-xchq-w5r3-4wg3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-32645"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:20.066924706Z"}}
