Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.neo4j:neo4j, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.neo4j:neo4j to 2026.01 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xr72-g735-4vwp is resolved across your whole dependency graph.
Workarounds
Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
