Attackers can send forged CloudEvents to the /namespaces/{ns}/eventbus/{name}/events or legacy /gateway/{name} paths, bypassing token authentication and authPublish checks, so they are stored and delivered to subscription sinks.","state":0,"publishedAt":"2026-10-18T11:38:25.071+00:00","modifiedAt":"2026-10-20T15:03:48.645+00:00","affected":[{"ecosystem":"Vendor product","name":"vanus","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"vanus-labs\",\n                    \"product\": \"vanus\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0.8.0\",\n                            \"lessThanOrEqual\": \"0.9.0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"repo\": \"https://github.com/vanus-labs/vanus\",\n                    \"packageURL\": \"pkg:golang/github.com/vanus-labs/vanus\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5,"severity":"HIGH"}],"references":["https://github.com/vanus-labs/vanus/issues/647","https://github.com/vanus-labs/vanus/blob/v0.9.0/internal/gateway/gateway.go#L81-L124","https://www.vulncheck.com/advisories/vanus-0.8.0-through-0.9.0-missing-authentication-via-gateway-cloudevents-http-receiver"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-111999","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-111999","identifiers":["CVE-2026-111999"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
