CVE-2026-111999

EUVD-2026-103452
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.
