CVE-2026-34220
CVE-2026-34220 is a SQL Injection vulnerability in @mikro-orm/core. O3 Security confirms whether CVE-2026-34220 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
MikroORM is vulnerable to SQL Injection via specially crafted object
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, a proxy for how much of the ecosystem is exposed.
@mikro-orm/corenpmDescription
MikroORM is a TypeScript ORM for Node.js based on Data Mapper, Unit of Work and Identity Map patterns. Prior to versions 6.6.10 and 7.0.6, there is a SQL injection vulnerability when specially crafted objects are interpreted as raw SQL query fragments. This issue has been patched in versions 6.6.10 and 7.0.6.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | @mikro-orm/core | all versions | 6.6.10 |
| 📦npm | @mikro-orm/core | ≥ 7.0.0-dev.0&&< 7.0.6 | 7.0.6 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @mikro-orm/core. 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 @mikro-orm/core to 6.6.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-34220 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-2026-34220 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-2026-34220. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
