Demonstrates concrete exploits: noSQL injection via aggressive input decoding in Rails/MongoDB that lets attackers bypass token checks and complete registrations or reset arbitrary passwords when defaults are nil; host header callback hijack that makes Twilio fetch attacker-controlled URLs to steal 2FA audio; PayPal IPN double spend where merchants fail to verify receiver_email so attacker’s valid PayPal IPN makes the merchant mark orders paid while funds go to attacker; shows Rails ActiveSupport MessageVerifier RCE from weak secrets and recommends long random secrets and JSON serializer.
