CVE-2026-34768: Electronjs Electron

High severity, CVSS 7.8. EPSS: 0.1% chance of exploitation in the next 30 days.

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.

Affected products

• Electronjs Electron: before 38.8.6 (fixed in 38.8.6); from 39.0.0, before 39.8.1 (fixed in 39.8.1); from 40.0.0, before 40.8.0 (fixed in 40.8.0); version 41.0.0 only
