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.","categories":["Unclassified"],"product":"motornet","vendor":"GDATASoftwareAG","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-112331","source_modified_at":"2026-10-23T13:28:32.139Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"motornet","vendor":"GDATASoftwareAG","versions":[{"status":"affected","version":"0","versionType":"semver","lessThan":"0.19.0"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-112331","source_modified_at":"2026-10-23T13:28:32.139Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"motornet","ecosystem":null},"version":"0.19.0","basis":"first unaffected version stated in the CVE record"}],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00679,"percentile":0.51803,"score_date":"2026-10-23"},"published_at":"2026-10-22T19:41:15.973Z","modified_at":"2026-10-23T13:28:32.139Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-112331","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T13:28:32.139Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-112331","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/GDATASoftwareAG/motornet/releases/tag/v0.19.0","tags":["release-notes","patch"]},{"source":"CVE List","url":"https://github.com/GDATASoftwareAG/motornet/pull/1785","tags":["issue-tracking","patch"]},{"source":"CVE List","url":"https://github.com/GDATASoftwareAG/motornet/commit/b4b6979f5dd7447dd02312e27d766ae2e9d050c2","tags":["patch"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/motor-net-kafka-denial-of-service-via-cloudevents-handler","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-23T13:28:32.139Z","content_hash":"243580043164a8e6325a7c803e39c3404ccf232e0dd71b7ca9e0fbbc41eea600"}}
