Description Doran Moppert 2018-03-14 02:04:17 UTC
Under certain circumstances the `fetch()` API can return transient local copies of resources that were sent with a `no-store` or `no-cache` cache header instead of downloading a copy from the network as it should. This can result in previously stored, locally cached data of a website being accessible to users if they share a common profile while browsing.
