CVE-2026-84993: SQL Injection (CVSS 6.5)

Description

MikroORM is a TypeScript ORM for Node.js based on Data Mapper, Unit of Work and Identity Map patterns. Prior to 6.6.16 and 7.1.7, the shared SQL layer validates the field key of an orderBy clause but does not validate its direction value before AbstractSqlPlatform.getOrderByExpression concatenates it into an ORDER BY clause. Applications that bind attacker-controlled request data to the direction in em.find(), em.findOne(), em.findAndCount(), QueryBuilder.orderBy(), or QueryBuilderHelper.getQueryOrderFromObject() can permit a raw SQL fragment that performs blind or boolean extraction of data available to the database account. The BaseMySqlPlatform and MsSqlPlatform fallthrough paths have the same behavior, affecting SQLite, PostgreSQL, MySQL, MariaDB, MSSQL, libSQL, and Oracle drivers, while MongoDB is not affected. This issue is fixed in versions 6.6.16 and 7.1.7.
