상세

### Impact Some window options supplied by web content in the `window.open()` features string were applied to the new `BrowserWindow` without an allowlist. Untrusted content could set window options it should not control, including options that cause the main process to access attacker-chosen file or network paths.

Apps are only affected if untrusted content can call `window.open()` and the app does not override child window options via `setWindowOpenHandler`. Apps that deny `window.open()` for untrusted content, or set `overrideBrowserWindowOptions` explicitly, are not affected.

### Workarounds Return `{ action: 'deny' }` from `setWindowOpenHandler` for untrusted content, or supply `overrideBrowserWindowOptions` so every window option is set explicitly.

### Fixed Versions * `42.0.0-beta.3` * `41.2.1` * `40.9.0` * `39.8.8`
