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":"2026-10-22T20:17:06.000Z","lastModified":"2026-10-23T17:06:36.000Z","status":"Deferred","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":8.7,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-755"],"affected":[],"epss":{"score":0.00679,"percentile":0.52077,"date":"2026-10-26","history":[{"date":"2026-10-23","score":0.00679,"percentile":0.51803}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.68%).
