Description

Impact

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.

Patches

  • 11.0.0-beta.1
  • 10.0.1
  • 9.3.0
  • 8.5.1

Workarounds

Sandbox all your iframes using the sandbox attribute. This will prevent them creating top-frame navigations and is good practice anyway.
