Description Doran Moppert 2020-07-29 07:03:13 UTC

Mozilla developer Anne van Kesteren discovered that `<iframe sandbox>` with the `allow-popups` flag could be bypassed when using `noopener` links. This could have led to security issues for websites relying on sandbox configurations that allowed popups and hosted arbitrary content.
