            "summary": "### Impact\n\nThe use of `Plug.Session` in `Pow.Plug.Session` is susceptible to session\nfixation attacks if a persistent session store is used for `Plug.Session`,\nsuch as Redis or a database. 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### References\n\nhttps://github.com/danschultzer/pow/commit/578ffd3d8bb8e8a26077b644222186b108da474f\nhttps://www.owasp.org/index.php/Session_fixation",
