CVE-2026-107375JHipster is a development platform to quickly generate, develop, and deploy modern web applications and microservice architectures. From 7.0.0 until 9.4.0, reactive applications generated with Spring WebFlux, Spring Data R2DBC, and a SQL database pass the attacker-controlled sort request parameter from paginated entity-list endpoints into createOrderByFields in generators/spring-boot/generators/data-relational/templates/src/main/java/package/repository/EntityManager_reactive.java.ejs. The generated code renders these properties into the SQL ORDER BY clause without validation or quoting, and the R2DBC simple query protocol can execute additional statements separated by semicolons. A normal authenticated user can consequently read sensitive tables, modify or delete data, or drop tables, while non-reactive JPA applications and NoSQL backends are outside this root cause. This issue is fixed in 9.4.0.
