CVE-2026-118487
Published:November 03, 2026
Updated:November 04, 2026
In Eclipse Vert.x versions [4.0.0, 4.5.35] or [5.0.0, 5.2.2], the "FrameParser" in vertx-stomp creates a "RecordParser" without setting "maxRecordSize", so any peer that streams bytes continuously without a newline character causes the parser to accumulate data indefinitely. 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.
