Summary

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.

Patch / fix

  • maven org.hibernate.reactive:hibernate-reactive-core 4.2.1
  • Red Hat Red Hat build of Quarkus 3.27.2.redhat 3.1.12.Final-redhat-00001
