{"id":"CVE-2026-103760","summary":"Mooncake transfer engine through 0.3.13.post1 Denial of Service via P2P Handshake Daemon Response Write","details":"Mooncake transfer engine through 0.3.13.post1 contains a denial of service vulnerability that allows unauthenticated remote attackers to block the handshake daemon by never reading replies. Attackers can send a Metadata request to the handshake RPC port and stall SocketHandShakePlugin's single listener thread in writeFully(), breaking all subsequent handshakes, metadata fetches, notify and probe requests.","modified":"2026-10-04T02:30:32.079864689Z","published":"2026-10-01T22:53:05.201Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-400"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/103xxx/CVE-2026-103760.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/103xxx/CVE-2026-103760.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-103760"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/mooncake-transfer-engine-through-0.3.13-post1-denial-of-service-via-p2p-handshake-daemon-response-write"},{"type":"REPORT","url":"https://github.com/kvcache-ai/Mooncake/issues/4443"},{"type":"PACKAGE","url":"https://github.com/kvcache-ai/Mooncake"},{"type":"ARTICLE","url":"https://github.com/kvcache-ai/Mooncake/blob/719735896c86b56fabec6cf3e825fb2ea640597a/mooncake-transfer-engine/src/transfer_metadata_plugin.cpp#L730-L803"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kvcache-ai/mooncake","events":[{"introduced":"0"},{"fixed":"719735896c86b56fabec6cf3e825fb2ea640597a"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"0"},{"last_affected":"0.3.13.post1"},{"fixed":"0.3.13.post1"}]}}],"versions":["v0.3.13-rc2","v0.3.13-rc1","v0.3.13","v0.3.12.post1","v0.3.11-rc1","v0.3.11.post1","v0.3.11","v0.3.10.post2","v0.3.10.post1","v0.3.10","v0.3.9","v0.3.8.post1","v0.3.8","v0.3.7.post2","v0.3.7.post1","v0.3.7","v0.3.6.post1","v0.3.6","v0.3.5","v0.3.4.post2","v0.3.4.post1","v0.3.4","v0.3.3.post2","v0.3.3.post1","v0.3.3","v0.3.2.post1","v0.3.2","v0.3.1","v0.3.0","v0.3.0-beta","v0.3.0-alpha","v0.2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-103760.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
