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.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","cwes":["CWE-306"],"vendors":[],"products":[],"references":[{"url":"https://github.com/vanus-labs/vanus/blob/v0.9.0/internal/gateway/gateway.go#L81-L124","tags":[]},{"url":"https://github.com/vanus-labs/vanus/issues/647","tags":[]},{"url":"https://www.vulncheck.com/advisories/vanus-0.8.0-through-0.9.0-missing-authentication-via-gateway-cloudevents-http-receiver","tags":[]}],"exploitRefs":[{"url":"https://github.com/vanus-labs/vanus/blob/v0.9.0/internal/gateway/gateway.go#L81-L124","tags":[]},{"url":"https://github.com/vanus-labs/vanus/issues/647","tags":[]}],"hasPoc":true,"ai":null}
