Description
The Authlogic gem for Ruby on Rails, when used with certain versions before 3.2.10, makes potentially unsafe find_by_id method calls, which might allow remote attackers to conduct CVE-2012-6496 SQL injection attacks via a crafted parameter in environments that have a known secret_token value, as demonstrated by a value contained in secret_token.rb in an open-source product.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for authlogic, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update authlogic to 3.3.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2012-6497 is resolved across your whole dependency graph.
Workarounds
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.
