{"id":"CVE-2026-70597","aliases":["GHSA-jm7p-cc5g-qwxx"],"url":"https://o3.security/vulnerability/CVE-2026-70597","summary":"Electron: Parent process code-sign check is spoofable","details":"### Impact\nOn macOS, the check Electron uses to confirm it was launched by a same-signed parent process could be bypassed by a local process. Apps that enable the fuse-based hardening restricting `ELECTRON_RUN_AS_NODE` and `NODE_OPTIONS` to same-signed parents rely on this check; a local attacker could bypass it and run their own code inside the signed app, inheriting its TCC permissions and keychain access.\n\nApps are only affected if they enable those macOS fuse-based restrictions. Apps that do not enable them are not affected.\n\n### Workarounds\nThere are no app side workarounds, you must update to a patched version of Electron.\n\n### Fixed Versions\n* `42.0.0-beta.3`\n* `41.2.1`\n* `40.9.0`\n* `39.8.8`\n\n### For more information\nIf you have any questions or comments about this advisory, email us at [security@electronjs.org](mailto:security@electronjs.org)","published":"2026-08-05T15:21:11.054Z","modified":"2026-10-28T10:55:16.700675897Z","cvss":{"score":6.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N"},"epss":{"score":0.00105,"percentile":0.01204,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"electron","fixedVersion":"39.8.8"},{"ecosystem":"npm","name":"electron","fixedVersion":"40.9.1"},{"ecosystem":"npm","name":"electron","fixedVersion":"41.2.1"},{"ecosystem":"npm","name":"electron","fixedVersion":"42.0.0-beta.3"}],"fix":{"url":"https://github.com/electron/electron/commit/0a6291a97d210db3733689e70a51f5711e38ed35","label":"electron/electron@0a6291a"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/70xxx/CVE-2026-70597.json"},{"type":"ADVISORY","url":"https://github.com/electron/electron/security/advisories/GHSA-jm7p-cc5g-qwxx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-70597"},{"type":"FIX","url":"https://github.com/electron/electron/commit/0a6291a97d210db3733689e70a51f5711e38ed35"},{"type":"PACKAGE","url":"https://github.com/electron/electron"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T10:55:16.700675897Z"}}
