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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-20"],"references":["https://github.com/vyperlang/vyper/security/advisories/GHSA-xchq-w5r3-4wg3","https://github.com/vyperlang/vyper/security/advisories/GHSA-xchq-w5r3-4wg3"],"products":["vyperlang:vyper"],"source":"nvd","synced_at":"2026-10-19T21:49:08.435428910+00:00"},"epss":{"cve":"CVE-2024-32645","score":0.00455,"percentile":0.3953,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-xchq-w5r3-4wg3","url":"https://osv.dev/vulnerability/GHSA-xchq-w5r3-4wg3","summary":"vyper performs incorrect topic logging in raw_log","modified":"2026-06-10T17:14:16.885616459Z","packages":[{"ecosystem":"PyPI","name":"vyper","purl":"pkg:pypi/vyper","ranges":["<0.4.0"],"fixed":["0.4.0"]}]},{"id":"PYSEC-2024-206","url":"https://osv.dev/vulnerability/PYSEC-2024-206","summary":"","modified":"2026-06-10T17:14:18.018997125Z","packages":[{"ecosystem":"PyPI","name":"vyper","purl":"pkg:pypi/vyper","ranges":["<0.4.0"],"fixed":["0.4.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
