The use of Plug.Session
in Pow.Plug.Session
is susceptible to session fixation attacks if a persistent session store is used for Plug.Session
, such as Redis or a database. Cookie store, which is used in most Phoenix apps, doesn't have this vulnerability.
Call Plug.Conn.configure_session(conn, renew: true)
periodically and after privilege change. A custom authorization plug can be written where the create/3
method should return the conn
only after Plug.Conn.configure_session/2
have been called on it.
