A security researcher exposes a critical flaw in an AI-generated SEO article by Safeguard.sh that incorrectly labels a remote code execution (RCE) vector as safe in Elixir. 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.
