ActiveRecord-JDBC-Adapter (AR-JDBC) lib/arjdbc/jdbc/adapter.rb sql.gsub() Function SQL Injection
Blast Radius

Description
ActiveRecord-JDBC-Adapter (AR-JDBC) contains a flaw that may allow carrying out an SQL injection attack. The issue is due to the sql.gsub() function in lib/arjdbc/jdbc/adapter.rb not properly sanitizing user-supplied input before using it in SQL queries. This may allow a remote attacker to inject or manipulate SQL queries in the back-end database, allowing for the manipulation or disclosure of arbitrary data.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for activerecord-jdbc-adapter. 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-jdbc-adapter to 1.2.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5qw5-wf2q-f538 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-5qw5-wf2q-f538 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-5qw5-wf2q-f538. 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-5qw5-wf2q-f538 in your dependencies?
O3 detects GHSA-5qw5-wf2q-f538 across RubyGems dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
