CVE-2018-1257

Spring Framework, versions 5.0.x prior to 5.0.6, versions 4.3.x prior to
4.3.17, and older unsupported versions allows applications to expose STOMP
over WebSocket endpoints with a simple, in-memory STOMP broker through the
spring-messaging module. A malicious user (or attacker) can craft a message
to the broker that can lead to a regular expression, denial of service
attack.
