Cookie store, which is used in most Phoenix\napps, doesn't have this vulnerability.\n\n### Workarounds\n\nCall `Plug.Conn.configure_session(conn, renew: true)` periodically and after\nprivilege change. A custom authorization plug can be written where the\n`create/3` method should return the conn only after\n`Plug.Conn.configure_session/2` have been called on it.\n\n###
