{"schema":"threatline.record/2","record":{"id":"CVE-2026-102672","aliases":["GHSA-vv43-5jgx-7qv8"],"summary":"Electron: Local race condition in Squirrel.Mac update installation on macOS","details":"### Impact\n\nOn macOS, Electron bundles the Squirrel.Mac auto-update framework, whose privileged `ShipIt` helper performs the final step of an update as root. A local attacker could cause that helper to overwrite a different application's files, as root, instead of the app that started the update. Exploitation requires local access to the machine.\n\nApps are only affected on macOS if they ship Squirrel.Mac-based auto-updates. Apps on other platforms, or that do not use Squirrel.Mac auto-updates, are not affected.\n\n### Workarounds\n\nThere are no app side workarounds, you must update to a patched version of Electron.\n\n### Fixed Versions\n\n* `42.0.0-beta.2`\n* `41.10.5`\n* `39.8.10`\n\n### For more information\n\nIf you have any questions or comments about this advisory, email us at
