Description

MikroORM is a TypeScript ORM for Node.js based on Data Mapper, Unit of Work and Identity Map patterns. Prior to @mikro-orm/knex 6.6.14 and @mikro-orm/sql 7.0.14, MikroORM's identifier-quoting helper (Platform.quoteIdentifier and the postgres/mssql overrides) and its JSON-path emitters (Platform.getSearchJsonPropertyKey, quoteJsonKey) did not properly escape characters that delimit the SQL identifier or string-literal context they emit into. When application code passes attacker-influenced strings to public ORM APIs that expect an identifier or a JSON-property filter, an attacker can break out of the quoted context and inject arbitrary SQL. This vulnerability is fixed in @mikro-orm/knex 6.6.14 and @mikro-orm/sql 7.0.14.

Affected products

@mikro-orm knex: before 6.6.14
mikro-orm: from 7.0.0-rc.0, < 7.0.14; before 6.6.14
@mikro-orm sql: before 7.0.14
