MikroORM vulnerabilities

MikroORM prior to versions 6.6.10 and 7.0.6 has a prototype pollution vulnerability in the Utils.merge helper used internally 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.

MikroORM, a TypeScript ORM for Node.js, has a SQL injection vulnerability in versions before 6.6.10 and 7.0.6. Specially crafted objects are interpreted as raw SQL query fragments.

MikroORM before versions 6.6.16 and 7.1.7 does not validate the direction value of an orderBy clause before concatenating it into an ORDER BY statement. Applications that bind attacker-controlled data to the sort direction in em.find(), em.findOne(), em.findAndCount(), QueryBuilder.orderBy(), or QueryBuilderHelper.getQueryOrderFromObject() may allow SQL fragment injection and blind data extraction.

In MikroORM before @mikro-orm/knex 6.6.14 and @mikro-orm/sql 7.0.14, the identifier-quoting functions and JSON-path emitters do not properly escape special characters. An application passing attacker-controlled data to public ORM APIs can lead to SQL injection.
