Rails Mass Assignment Companion
FreeRuby Security
Warning on params.permit! (or xxx_params.permit!): Rails' own official documentation states: "Extreme care should be taken when using permit!, as it will allow all current and future model attributes to be mass-assigned". This is the exact anti-pattern strong parameters exist to prevent: it disables the whitelist entirely, permitting whatever attributes an attacker sends in the request body,
The gap it fixes
ruby def user_params params.permit! end
