Summary

Electron: Unquoted executable path in app.setLoginItemSettings on Windows

Details

Impact

On Windows, app.setLoginItemSettings({openAtLogin: true}) wrote the executable path to the Run registry key without quoting. If the app is installed to a path containing spaces, an attacker with write access to an ancestor directory may be able to cause a different executable to run at login instead of the intended app.

On a default Windows install, standard system directories are protected against writes by standard users, so exploitation typically requires a non-standard install location.

Workarounds

Install the application to a path without spaces, or to a location where all ancestor directories are protected against unauthorized writes.

Fixed Versions

41.0.0-beta.8
40.8.0
39.8.1
38.8.6

CVE-2026-34768 (GCVE-0-2026-34768)

Vulnerability from cvelistv5 – Published: 2026-04-03 23:44 – Updated: 2026-04-06 19:08

Title

Electron: Unquoted executable path in app.setLoginItemSettings on Windows

Summary

Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 38.8.6, 39.8.1, 40.8.0, and 41.0.0-beta.8, on Windows, app.setLoginItemSettings({openAtLogin: true}) wrote the executable path to the Run registry key without quoting. If the app is installed to a path containing spaces, an attacker with write access to an ancestor directory may be able to cause a different executable to run at login instead of the intended app. On a default Windows install, standard system directories are protected against writes by standard users, so exploitation typically requires a non-standard install location. This issue has been patched in versions 38.8.6, 39.8.1, 40.8.0, and 41.0.0-beta.8.
