Since
binary_to_termisErlangAPI I would recommend to read:erlangmodule documentation:voltone

For those coming from google,
NOT SAFE:
:erlang.binary_to_term(user_input, [:safe])SAFE:
Plug.Crypto.non_executable_binary_to_term(user_input, [:safe])This is extremely important if your application passes user input to binary_to_term. The $425 million Equifax breach happened due to an Apache Struts web app that was vulnerable to RCE. Java is to Struts what Ruby is to Rails and Elixir is to Phoenix.
