CVE-2020-15174 Information

Description

In Electron before versions 11.0.0-beta.1 10.0.1 9.3.0 or 8.5.1 the will-navigate event that apps use to prevent navigations to unexpected destinations as per our security recommendations can be bypassed when a sub-frame performs a top-frame navigation across sites. The issue is patched in versions 11.0.0-beta.1 10.0.1 9.3.0 or 8.5.1 As a workaround sandbox all your iframes using the sandbox attribute. This will prevent them creating top-frame navigations and is good practice anyway.
