The library directly interpolates these values into dynamically generated code without sanitization, enabling attackers to execute arbitrary code in the context of the Node.js process.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","score":6.5},"cwes":["CWE-94"],"references":["https://github.com/keichi/binary-parser","https://github.com/keichi/binary-parser/pull/283","https://kb.cert.org/vuls/id/102648","https://www.npmjs.com/package/binary-parser","https://www.kb.cert.org/vuls/id/102648"],"products":["keichi:binary-parser"],"source":"nvd","synced_at":"2026-10-19T22:21:16.563232421+00:00"},"epss":{"cve":"CVE-2026-1245","score":0.00563,"percentile":0.46833,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-m39p-34qh-rh3w","url":"https://osv.dev/vulnerability/GHSA-m39p-34qh-rh3w","summary":"binary-parser library has a code injection vulnerability","modified":"2026-02-03T03:11:22.190245Z","packages":[{"ecosystem":"npm","name":"binary-parser","purl":"pkg:npm/binary-parser","ranges":["<2.3.0"],"fixed":["2.3.0"]}]}],"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).
