Detailsinfo

A vulnerability classified as critical was found in MikroORM up to 6.6.15/7.1.6. Affected by this vulnerability is the function em.find/em.findOne/em.findAndCount/QueryBuilder.orderBy/QueryBuilderHelper.getQueryOrderFromObject of the component Shared SQL Layer. The manipulation of the argument direction with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.
