Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
n8nnpmDescription
n8n before 1.123.67, 2.31.5, and 2.32.1 contains a SQL injection vulnerability in the Snowflake node's Execute Query operation, which interpolates expression values directly into the SQL string. When a workflow author embeds untrusted, externally-controlled expression data directly in a raw SQL query, that data is not parameterized, allowing SQL injection. The fix adds an optional 'Query Parameters' field to bind values via positional placeholders.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for n8n. 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 n8n to 1.123.67 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-72750 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 CVE-2026-72750 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 CVE-2026-72750. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
