# CVE-2026-34220: MikroORM is vulnerable to SQL Injection via specially crafted object

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- 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.

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

- npm `@mikro-orm/core` < 6.6.10 → fixed: 6.6.10
- npm `@mikro-orm/core` >= 7.0.0-dev.0, < 7.0.6 → fixed: 7.0.6

## Affected products (CVE record)

- mikro-orm mikro-orm: < 6.6.10, >= 7.0.0-rc.0, < 7.0.6

## Severity

- GitHub_M CVSS 4.0: 9.3 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N`
- CISA-ADP CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
- GitHub CVSS 4.0: 9.3 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.47% probability of exploitation activity in the next 30 days; percentile 39.
