CVE-2026-70597
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.
