How to Fix CVE-2026-102675

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: 41.10.6 
npm install electron@41.10.6
electron fixed: 42.9.2 
npm install electron@42.9.2
electron fixed: 43.4.1 
npm install electron@43.4.1
electron fixed: 44.0.0-beta.5 
npm install electron@44.0.0-beta.5
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-2026-102675, 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 41.10.6), 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-346: Origin Validation Error, where the product does not properly verify that the source of data or communication is valid. 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 Responses served through `protocol.registerFileProtocol` or `protocol.registerHttpProtocol` for a custom scheme registered with `supportFetchAPI: true` but without `corsEnabled: true` could be read cross-origin by web content. This completes the fix for CVE-2026-70604. Apps are only affected if they register such a scheme, serve it through one of those handlers, and load untrusted content. Apps that set `corsEnabled: true`, or that do not load untrusted content, are not affected. ### Workarounds Set `corsEnabled: true` on the scheme, or do not load untrusted content in windows that can reach it. ### Fixed Versions * `44.0.0-beta.5` * `43.4.1` * `42.9.2` * `41.10.6` ### For more information If you have any questions or comments about this advisory, email us at [security@electronjs.org](mailto:security@electronjs.org)
