CVE-2013-0233
CVE-2013-0233 is a CWE-399 vulnerability in devise. 3 public exploit references exist, so weaponization risk is real. O3 Security confirms whether CVE-2013-0233 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Devise does not properly perform type conversion when performing database queries

devise💎devise💎devise💎deviseReal-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
Devise gem 2.2.x before 2.2.3, 2.1.x before 2.1.3, 2.0.x before 2.0.5, and 1.5.x before 1.5.4 for Ruby, when using certain databases, does not properly perform type conversion when performing database queries, which might allow remote attackers to cause incorrect results to be returned and bypass security checks via unknown vectors, as demonstrated by resetting passwords of arbitrary accounts.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 💎RubyGems | devise | ≥ 2.2.0&&< 2.2.3 | 2.2.3 |
| 💎RubyGems | devise | ≥ 2.1.0&&< 2.1.3 | 2.1.3 |
| 💎RubyGems | devise | ≥ 2.0.0&&< 2.0.5 | 2.0.5 |
| 💎RubyGems | devise | ≥ 1.5.0&&< 1.5.4 | 1.5.4 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for devise. 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 devise to 2.2.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2013-0233 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-2013-0233 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-2013-0233. 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-2013-0233 in your dependencies?
O3 detects CVE-2013-0233 across RubyGems dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
