CVE-2026-118487

HighCVSS 7.5/10Last modified Nov 3, 2026

Description

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.
