  "title": "Missing authentication for event publishing in Vanus gateway",
  "summary": "Vanus 0.8.0 through 0.9.0 does not properly require authentication when publishing through the gateway CloudEvents HTTP receiver. A remote unauthenticated party that can reach the receiver can inject events into event buses, potentially causing delivery to configured subscription sinks.",
  "mitigation": "Do not expose the affected gateway receiver to untrusted networks; restrict access to trusted publishers and enforce authentication at a reverse proxy or network boundary. Upgrade to a vendor-fixed release when one is available; no fixed version is recorded in the advisory.",
