Who should care

Organizations running YunaiV yudao-cloud 2026.03 with exposed Admin API endpoints; security teams monitoring for SSRF vulnerabilities in IoT data pipeline configurations; administrators responsible for API gateway security and outbound request controls

Technical summary

The vulnerability resides in the IotDataSinkHttpConfig function of the yudao-cloud Admin API. An attacker with high privileges can manipulate HTTP sink configuration parameters to induce the server to make requests to arbitrary destinations. The attack vector is network-based with low attack complexity, requiring no user interaction but high privileges. The vulnerability has public exploit availability, increasing practical risk despite the low CVSS base score.

Defensive priority

low

Recommended defensive actions

  • Review and restrict network access to the /admin-api/iot/data-sink/create endpoint
  • Implement input validation and URL allowlisting for the IotDataSinkHttpConfig function
  • Apply principle of least privilege to Admin API access
  • Monitor for unauthorized outbound requests from application servers
  • Contact YunaiV vendor for patch availability and security updates
  • Consider implementing SSRF protection mechanisms such as URL parsing validation and DNS rebinding protections
