No CVSS score has been assigned to CVE-2012-2695 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2012-2695?

CVE-2012-2695 affects the following packages: activerecord (RubyGems), activerecord (RubyGems), activerecord (RubyGems), activerecord (RubyGems). Ecosystems affected: RubyGems.

How do I fix CVE-2012-2695?

Update activerecord to 3.0.14 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2012-2695 is resolved across your whole dependency graph.

How do I detect CVE-2012-2695 in my RubyGems dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for activerecord, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2012-2695 if there is no patch (or I can't update yet)?

Until you can upgrade, make sure every query built from user input uses parameterised statements or a prepared-statement API rather than string concatenation, and reduce the database account's privileges so an injected query cannot read or alter data beyond what the feature needs.

Is CVE-2012-2695 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2012-2695, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2012-2695?

CVE-2012-2695 has an EPSS (Exploit Prediction Scoring System) score of 2.9%, placing it in the 87th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2012-2695?

CVE-2012-2695 is classified as SQL Injection (CWE-89). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2012-2695 published, and has it been updated?

CVE-2012-2695 was published on October 24, 2017 and was last updated on January 21, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

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.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
