CVE-2026-102672
Published:September 29, 2026
Updated:September 30, 2026
On 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. Apps 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.
