By setting the content-type header to application/cloudevents+json and omitting required CloudEvent attributes (id, source, type), the attacker triggers an ArgumentException in KafkaMessageConsumer.SingleMessageHandlingAsync that is treated as fatal, causing the host to stop and re-process the same poison record on every restart, resulting in a permanent crash-loop.","published":"2026-10-22T20:17:05.750","modified":"2026-10-22T20:17:05.750","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/GDATASoftwareAG/motornet/commit/b4b6979f5dd7447dd02312e27d766ae2e9d050c2","label":"GDATASoftwareAG/motornet@b4b6979"},"references":[{"type":"WEB","url":"https://github.com/GDATASoftwareAG/motornet/commit/b4b6979f5dd7447dd02312e27d766ae2e9d050c2"},{"type":"WEB","url":"https://github.com/GDATASoftwareAG/motornet/pull/1785"},{"type":"WEB","url":"https://github.com/GDATASoftwareAG/motornet/releases/tag/v0.19.0"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/motor-net-kafka-denial-of-service-via-cloudevents-handler"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-22T20:17:05.750"}}
