Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 41.10.6, 42.9.2, 43.4.1, and 44.0.0-beta.5, responses served through protocol.registerFileProtocol or protocol.registerHttpProtocol for a custom scheme registered with supportFetchAPI enabled but corsEnabled disabled could remain script-readable across origins. This residual issue completes the remediation for CVE-2026-70604. Applications are affected only when they expose such a scheme and load untrusted content in the same session. Schemes intentionally registered with corsEnabled enabled remain cross-origin readable by design. This issue is fixed in versions 41.10.6, 42.9.2, 43.4.1, and 44.0.0-beta.5.

GHSA-j84w-jfhq-vhvj — Electron: File and HTTP protocol handlers allow cross-origin reads without corsEnabled

Affected: npm: electron

### 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`
