CVE-2026-34768

Описание

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.

A flaw was found in Electron. On Windows, when an application is installed to a path containing spaces and configured to open at login, the executable path is written to the system's Run registry key without proper quoting. An attacker with write access to an ancestor directory can exploit this to cause a different, malicious executable to run at login instead of the intended application, potentially leading to arbitrary code execution. Exploitation typically requires a non-standard installation location.
