Horizon Alert
Summary of the vulnerability and why it matters
The Relay Server has an authentication bypass flaw that could allow unauthorized access to documents. This is concerning because it means someone could potentially read or change your team's shared content without permission.
- Unauthenticated access to documents.
- Can read or modify document contents.
- Affects real-time collaboration features.
Attack Path
How an attacker could exploit the issue
An unauthenticated attacker could exploit this by connecting to a Relay server's WebSocket endpoint and manipulating document content if they can guess a document ID. This bypasses the need for any valid authentication or authorization.
- Network access required.
- Target document sync WebSocket.
- Guess document ID.
Live Threat
Current exploitation, exposure, and threat context
The current threat picture indicates a significant risk due to an authentication bypass vulnerability in Relay Server. Attackers can exploit this to gain unauthorized access to real-time collaborative documents, potentially leading to data compromise. The vulnerability is exploitable over the network without requiring user interaction or prior privileges.
- Exploitable without authentication.
- Real-time collaboration services targeted.
- Fix available in 0.9.7.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
Prioritize patching Relay Server to version 0.9.7 to address the authentication bypass vulnerability. If patching is delayed, implement network segmentation to isolate affected servers and strictly monitor for unauthorized WebSocket connections on document sync endpoints.
- Apply patch 0.9.7 immediately.
- Block unauthenticated WebSocket connections.
- Monitor WebSocket traffic for anomalies.
