Should you act?
Critical and remotely reachable
No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.5%, percentile 39: FIRST’s model estimates a 0.5% chance of exploitation activity in the next 30 days, higher than 39% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes
@mikro-orm/core(npm) < 6.6.10, fixed in 6.6.10;@mikro-orm/core(npm) >= 7.0.0-dev.0, < 7.0.6, fixed in 7.0.6. Check your lockfile, including transitive dependencies.
What it is
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.
From the GitHub advisory
Summary
MikroORM versions
Impact
If user-controlled input is passed directly to MikroORM query construction APIs, an attacker may inject raw SQL fragments. This can lead to SQL injection depending on the database and query being executed.
Affected usage
Weakness type: CWE-89.
