CVE-2020-15174  (opens in a new tab)
CWE-284  (opens in a new tab)

How to fix?

Upgrade electron/electron to version 8.5.1, 9.3.0, 10.0.1 or higher.

Overview

Affected versions of this package are vulnerable to Access Restriction Bypass. 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.
