CVE-2026-102675 (CVSS 7.4)

Description

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.
