Both the STOMP server and the STOMP client are affected: a malicious server can exploit this against a connecting client, and a malicious client can exploit this against a server before or after authentication. Sustained byte streaming exhausts JVM heap memory, crashing the affected process and causing a complete denial of service."}], "lastModified": "2026-11-03T16:30:17.150", "sourceIdentifier": "emo@eclipse.org"}
