How to Fix CVE-2026-34768

To remediate this vulnerability, upgrade all affected Electron dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

electron fixed: 38.8.6
npm install electron@38.8.6
electron fixed: 39.8.1
npm install electron@39.8.1
electron fixed: 40.8.0
npm install electron@40.8.0
electron fixed: 41.0.0-beta.8
npm install electron@41.0.0-beta.8
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

npm ls electron

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-34768, inspect your project dependencies using npm:

npm ls electron

Analyze the terminal output to locate any version of Electron in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 38.8.6), your application is affected.

Note: The npm ls electron command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-428: Unquoted Search Path or Element, where the product uses a search path that contains an unquoted element, in which the element contains whitespace or other separators. this can cause the product to access resources in a parent path. In Electron, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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` ### For more information If there are any questions or comments about this advisory, send an email to [security@electronjs.org](mailto:security@electronjs.org)
