Official description

A flaw was found in Hibernate Reactive. When an HTTP endpoint is exposed to perform database operations, a remote client can prematurely close the HTTP connection. This action may lead to leaking connections from the database connection pool, potentially causing a Denial of Service (DoS) by exhausting available database connections.
