Unauthorized event access via missing WebSocket origin validation
Published Aug 26, 2026 · Updated Aug 27, 2026
Cross-domain policy failure in Cohere North AI 1.1.5 allows remote attackers to access internal events through its WebSocket endpoint. The /admin/api/_event WebSocket endpoint accepts upgrade requests without validating the Origin header, so untrusted sites can connect and exchange messages. An attacker-controlled page must run in a browser that can reach the endpoint, exposing real-time events or data streams and permitting unintended API actions.
