GHSA-3crr-9vmg-864v
GHSA-3crr-9vmg-864v is a Improper Input Validation vulnerability in activerecord. O3 Security confirms whether GHSA-3crr-9vmg-864v is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Active Record Improper Input Validation
Blast Radius
activerecord💎activerecord💎activerecordReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects RubyGems packages — download data is not available via public APIs for these ecosystems.
Description
The Active Record component in Ruby on Rails 2.3.x before 2.3.18, 3.1.x before 3.1.12, and 3.2.x before 3.2.13 processes certain queries by converting hash keys to symbols, which allows remote attackers to cause a denial of service via crafted input to a where method.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 💎RubyGems | activerecord | ≥ 2.3.0&&< 2.3.18 | 2.3.18 |
| 💎RubyGems | activerecord | ≥ 3.1.0&&< 3.1.12 | 3.1.12 |
| 💎RubyGems | activerecord | ≥ 3.2.0&&< 3.2.13 | 3.2.13 |
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 2.3.18 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3crr-9vmg-864v 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 GHSA-3crr-9vmg-864v 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 GHSA-3crr-9vmg-864v. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-3crr-9vmg-864v in your dependencies?
O3 detects GHSA-3crr-9vmg-864v across RubyGems dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
