Name of the Vulnerable Software and Affected Versions Electron versions prior to 11.0.0-beta.1 Electron versions prior to 10.0.1 Electron versions prior to 9.3.0 Electron versions prior to 8.5.1

Description The will-navigate event can be bypassed when a sub-frame performs a top-frame navigation across sites. This issue can be exploited to bypass navigation restrictions. As a workaround, sandboxing all iframes using the sandbox attribute can prevent them from creating top-frame navigations.

Recommendations For versions prior to 11.0.0-beta.1, update to version 11.0.0-beta.1 or later. For versions prior to 10.0.1, update to version 10.0.1 or later. For versions prior to 9.3.0, update to version 9.3.0 or later. For versions prior to 8.5.1, update to version 8.5.1 or later. As a temporary workaround, consider sandboxing all iframes using the sandbox attribute to prevent them from creating top-frame navigations.
