Proactive Monitoring: Monitor network traffic for excessive requests to the /api/block/ and /api/file/ endpoints, especially from unrecognized IP addresses.

Compensating Controls: If the application is hosted on a network, use an authentication proxy or VPN to restrict access to the SiYuan web interface to authorized users only.

Exploitation Status

Public Exploit Available: false

Analyst Notes: As of Mar 26, 2026, there is no public information indicating active exploitation of this vulnerability. However, due to the nature of the flaw, the potential for exploitation is high.

Analyst Recommendation

Because SiYuan is often used to store highly sensitive personal or organizational data, this unauthenticated access flaw is critical. Users should update immediately and ensure their instances are not exposed to the public internet without additional layers of authentication.
