Description
The DBCPConnectionPool and HikariCPConnectionPool Controller Services in Apache NiFi 0.0.2 through 1.21.0 allow an authenticated and authorized user to configure a Database URL with the H2 driver that enables custom code execution.
The resolution validates the Database URL and rejects H2 JDBC locations.
You are recommended to upgrade to version 1.22.0 or later which fixes this issue.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.nifi:nifi-dbcp-base, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.apache.nifi:nifi-dbcp-base to 1.22.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xm2m-2q6h-22jw 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-xm2m-2q6h-22jw can be triaged on real exposure rather than presence alone.
Tailored to GHSA-xm2m-2q6h-22jw. 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-xm2m-2q6h-22jw in your dependencies?
O3 Security finds GHSA-xm2m-2q6h-22jw across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
