GHSA-rcpf-vj53-7h2m Denial of Service in org.springframework:spring-core

• Maven org.springframework:spring-core: >= 5.0.0, < 5.0.6 → fixed in 5.0.6 • Maven org.springframework:spring-core: < 4.3.17 → fixed in 4.3.17

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.
