The article marks `:erlang.binary_to_term(untrusted, [:safe])` as safe, when in fact it allows attackers to execute arbitrary code via anonymous functions — a vulnerability previously documented as CVE-2020-15150. The correct safe alternative is `Plug.Crypto.non_executable_binary_to_term/2`. The dangerous post ranks first on Google for Elixir Phoenix security best practices, posing a real risk to developers and AI coding agents who may implement the flawed guidance. ## Full article daily.dev links to this article rather than hosting it.
