{"id":"CVE-2026-111999","summary":"Vanus 0.8.0 through 0.9.0 Missing Authentication via Gateway CloudEvents HTTP Receiver","details":"Vanus 0.8.0 through 0.9.0 contains a missing authentication vulnerability that allows unauthenticated remote attackers to publish events to any eventbus through the gateway CloudEvents HTTP receiver. 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.","modified":"2026-10-19T02:45:44.888692828Z","published":"2026-10-18T11:38:25.071Z","database_specific":{"cwe_ids":["CWE-306"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111999.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111999.json"},{"type":"PACKAGE","url":"https://github.com/vanus-labs/vanus"},{"type":"ARTICLE","url":"https://github.com/vanus-labs/vanus/blob/v0.9.0/internal/gateway/gateway.go#L81-L124"},{"type":"REPORT","url":"https://github.com/vanus-labs/vanus/issues/647"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111999"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/vanus-0.8.0-through-0.9.0-missing-authentication-via-gateway-cloudevents-http-receiver"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/vanus-labs/vanus","events":[{"introduced":"d35053c35b480a011083395aa9ac688ef65b8b32"},{"last_affected":"d76dc3af1f33225d87bee16a60f6918c046cba17"}],"database_specific":{"extracted_events":[{"introduced":"0.8.0"},{"last_affected":"0.9.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v0.9.0","raft/v0.9.0","proto/v0.9.0","pkg/v0.9.0","observability/v0.9.0","client/v0.9.0","v0.8.0","raft/v0.8.0","proto/v0.8.0","pkg/v0.8.0","observability/v0.8.0","client/v0.8.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-111999.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
