CVE-2026-34768
LowCVSS 3.9Exploitation Probability (EPSS)
Low risk3th percentile - higher than 3% of all known CVEs
Summary
Electron on Windows fails to quote the executable path when writing to the Run registry key, allowing an attacker with write access to an ancestor directory to replace the startup executable.
Risk Assessment
If the app is installed in a path with spaces, an attacker could cause a malicious executable to run at login instead of the intended app.
Recommendation
Update Electron to versions 38.8.6, 39.8.1, 40.8.0, or 41.0.0-beta.8 which fix the path quoting issue.
Original NVD description (English source)
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.
