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."}],"source":{"advisory":"GHSA-jm7p-cc5g-qwxx","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-05T00:00:00+00:00","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3","id":"CVE-2026-70597"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-06T03:55:28.858Z"}}]}}
