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.","published":"2026-10-18T11:38:25.071Z","modified":"2026-10-19T02:45:44.888692828Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-19T02:45:44.888692828Z"}}
