CVE-2014-3514
CVE-2014-3514 is a CWE-264 vulnerability in activerecord. O3 Security confirms whether CVE-2014-3514 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Active Record subject to strong parameters protection bypass

Description
activerecord/lib/active_record/relation/query_methods.rb in Active Record in Ruby on Rails 4.0.x before 4.0.9 and 4.1.x before 4.1.5 allows remote attackers to bypass the strong parameters protection mechanism via crafted input to an application that makes create_with calls.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 💎RubyGems | activerecord | ≥ 4.0.0&&< 4.0.9 | 4.0.9 |
| 💎RubyGems | activerecord | ≥ 4.1.0&&< 4.1.5 | 4.1.5 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for activerecord. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update activerecord to 4.0.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2014-3514 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2014-3514 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2014-3514. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2014-3514 in your dependencies?
O3 detects CVE-2014-3514 across RubyGems dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
