CVE-2020-15174 – Unpreventable top-level navigation in Electron

https://notcve.org/view.php?id=CVE-2020-15174

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. En Electron anteriores a las versiones 11.0.0-beta.1, 10.0.1, 9.3.0 o 8.5.1, el evento "will-navigate" que usa las aplicaciones para evitar la navegación a destinos inesperados según nuestras recomendaciones de seguridad se puede omitir cuando una sub-frame realiza una navegación top-frame a través de los sitios. El problema está parcheado en las versiones 11.0.0-beta.1, 10.0.1, 9.3.0 o 8.5.1. • https://github.com/electron/electron/commit/18613925610ba319da7f497b6deed85ad712c59b https://github.com/electron/electron/security/advisories/GHSA-2q4g-w47c-4674 • CWE-20: Improper Input Validation CWE-693: Protection Mechanism Failure •
