Description

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 [email protected]
