Brakeman - Rails Security Scanner

Static analysis security scanner for Ruby on Rails

Format Validation

Calls to validates_format_of ..., :with => // which do not use \A and \z as anchors will cause this warning. Using ^ and $ is not sufficient, as they will only match up to a new line. This allows an attacker to put whatever malicious input they would like before or after a new line character.

See the Ruby Security Guide for details.
