Details

As written in the advisory (Markdown source, shown as plain text).

### Impact The `will-navigate` event that apps use to prevent navigations to unexpected destinations [as per our security recommendations](https://www.electronjs.org/docs/tutorial/security) can be bypassed when a sub-frame performs a top-frame navigation across sites. ### Patches * `11.0.0-beta.1` * `10.0.1` * `9.3.0` * `8.5.1` ### Workarounds Sandbox all your iframes using the [`sandbox` attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe#attr-sandbox). This will prevent them creating top-frame navigations and is good practice anyway. ### For more information If you have any questions or comments about this advisory: * Email us at [email protected]
