{"cve":"CVE-2023-32675","nvd":{"published":"2023-05-19T20:15:09.230","modified":"2026-06-17T05:59:21.897","status":"Modified","description":"Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. In contracts with more than one regular nonpayable function, it is possible to send funds to the default function, even if the default function is marked `nonpayable`. This applies to contracts compiled with vyper versions prior to 0.3.8. This issue was fixed by the removal of the global `calldatasize` check in commit `02339dfda`. Users are advised to upgrade to version 0.3.8. Users unable to upgrade should avoid use of nonpayable default functions.","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-670"],"references":["https://github.com/vyperlang/vyper/commit/02339dfda0f3caabad142060d511d10bfe93c520","https://github.com/vyperlang/vyper/security/advisories/GHSA-vxmm-cwh2-q762","https://github.com/vyperlang/vyper/commit/02339dfda0f3caabad142060d511d10bfe93c520","https://github.com/vyperlang/vyper/security/advisories/GHSA-vxmm-cwh2-q762"],"products":["vyperlang:vyper"],"source":"nvd","synced_at":"2026-10-19T21:38:18.424950729+00:00"},"epss":{"cve":"CVE-2023-32675","score":0.00553,"percentile":0.46201,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-vxmm-cwh2-q762","url":"https://osv.dev/vulnerability/GHSA-vxmm-cwh2-q762","summary":"Vyper's nonpayable default functions are sometimes payable","modified":"2026-02-22T22:56:18.898601Z","packages":[{"ecosystem":"PyPI","name":"vyper","purl":"pkg:pypi/vyper","ranges":["<0.3.8"],"fixed":["0.3.8"]}]},{"id":"PYSEC-2023-80","url":"https://osv.dev/vulnerability/PYSEC-2023-80","summary":"","modified":"2026-02-22T22:49:58.694830Z","packages":[{"ecosystem":"PyPI","name":"vyper","purl":"pkg:pypi/vyper","ranges":["<0.3.8"],"fixed":["0.3.8"]}]}],"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).
