{"cve":"CVE-2026-70597","nvd":{"published":"2026-08-05T16:17:03.603","modified":"2026-10-08T13:47:07.080","status":"Analyzed","description":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.8, 40.9.0, 41.2.1, and 42.0.0-beta.3, the check Electron uses on macOS to confirm it was launched by a same-signed parent process could be bypassed by a local process. Apps that enable fuse-based hardening restricting ELECTRON_RUN_AS_NODE and NODE_OPTIONS to same-signed parents rely on this check, and a local attacker could bypass it and run code inside the signed app, inheriting its TCC permissions and keychain access. This issue is fixed in 39.8.8, 40.9.0, 41.2.1, and 42.0.0-beta.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","score":6.3},"cwes":["CWE-367"],"references":["https://github.com/electron/electron/commit/0a6291a97d210db3733689e70a51f5711e38ed35","https://github.com/electron/electron/security/advisories/GHSA-jm7p-cc5g-qwxx"],"products":["electronjs:electron"],"source":"nvd","synced_at":"2026-10-19T22:47:10.050265369+00:00"},"epss":{"cve":"CVE-2026-70597","score":0.00104,"percentile":0.00999,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-jm7p-cc5g-qwxx","url":"https://osv.dev/vulnerability/GHSA-jm7p-cc5g-qwxx","summary":"Electron: Parent process code-sign check is spoofable","modified":"2026-08-05T15:41:04.630203Z","packages":[{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":["<39.8.8"],"fixed":["39.8.8"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=40.0.0-alpha.1 <40.9.1"],"fixed":["40.9.1"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=41.0.0-alpha.1 <41.2.1"],"fixed":["41.2.1"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=42.0.0-alpha.1 <42.0.0-beta.3"],"fixed":["42.0.0-beta.3"]}]}],"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).
