CVE-2012-2695: activerecord vulnerable to SQL Injection

October 24, 2017 (updated January 21, 2025)

The Active Record component in Ruby on Rails efore 2.3.15, 3.0.x before 3.0.14, 3.1.x before 3.1.6, and 3.2.x before 3.2.6 does not properly implement the passing of request data to a where method in an ActiveRecord class, which allows remote attackers to conduct certain SQL injection attacks via nested query parameters that leverage improper handling of nested hashes, a related issue to CVE-2012-2661.
