As a result, child processes (e.g. npm install, postUpgradeTasks, postUpdateOptions) gain full access to all environment variables of the Renovate process, allowing insider or outside attackers to exfiltrate secrets accessible to the Renovate deployment.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":6.8},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":5.5},"cwes":["CWE-526"],"references":["https://github.com/renovatebot/renovate/security/advisories/GHSA-8wc6-vgrq-x6cf","https://www.vulncheck.com/advisories/renovate-before-environment-variable-exposure"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-76227","score":0.00154,"percentile":0.0449,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-8wc6-vgrq-x6cf","url":"https://osv.dev/vulnerability/GHSA-8wc6-vgrq-x6cf","summary":"Child processes spawned by Renovate incorrectly have full access to environment variables","modified":"2026-08-20T04:04:14.766445851Z","packages":[{"ecosystem":"npm","name":"renovate","purl":"pkg:npm/renovate","ranges":[">=42.68.1 <42.96.3"],"fixed":["42.96.3"]},{"ecosystem":"npm","name":"renovate","purl":"pkg:npm/renovate","ranges":[">=43.0.0 <43.4.4"],"fixed":["43.4.4"]}]}],"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).
