Vulnerability description

DayBreach CVE AI Research

CVE-2026-102672 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.

### Impact 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. ### Workarounds There are no app side workarounds, you must update to a patched version of Electron. ### Fixed Versions * `42.0.0-beta.2` * `41.10.5` * `39.8.10` ### For more information If you have any questions or comments about this advisory, email us at [security@electronjs.org](mailto:security@electronjs.org)
