Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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, a prototype pollution vulnerability exists in the Utils.merge helper
used internally by MikroORM when merging object structures. The function did not prevent special keys such
as __proto__, constructor, or prototype, allowing attacker-controlled input to modify the JavaScript
object prototype when merged. This issue has been patched in versions 6.6.10 and 7.0.6. (CVE-2026-34221)

Solution

Update the @mikro-orm/core library and its related packages to version 6.6.10 or later.
