Executive brief
Cohere North AI, an enterprise AI platform for business workflow automation, contains a misconfiguration that allows WebSocket connections from any origin without validation. An attacker from an untrusted website can establish connections to the platform's internal APIs and access real-time events or manipulate system behavior, potentially exposing sensitive data or enabling unauthorized actions within customer deployments.
Technical details
The vulnerability is an improper cross-domain policy configuration (CWE-942) in the WebSocket endpoint (wss://example.com/admin/api/_event/?EIO=4&transport=websocket). The server fails to validate the Origin header of incoming WebSocket upgrade requests, allowing connections from any external domain. An unauthenticated attacker can establish a WebSocket connection from a malicious website and interact with internal APIs to access event streams and system state. The root cause is the absence of origin-based access controls on the WebSocket server. Patches or mitigations have not yet been confirmed as available.
