Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Hibernate Reactive (org.hibernate.reactive:hibernate-reactive-core) versions before 4.2.1 are affected. A remote client that prematurely closes an HTTP connection to an endpoint performing database operations can cause database connections to leak from the connection pool, leading to denial of service by exhausting available connections. Upgrade to version 4.2.1 or later.
