Executive Summary

This is an authenticated Server-Side Request Forgery (SSRF) vulnerability in the sdcb/chats application up to version 1.12.0. It exists in the MCP tool discovery endpoint (POST /api/mcp/fetch-tools) which is accessible to any authenticated user due to weak authorization controls. The endpoint accepts arbitrary URLs in requests, allowing the backend to initiate HTTP requests to internal or external services without restrictions.

Detection Guidance

To detect this SSRF vulnerability in sdcb chats, check if the POST /api/mcp/fetch-tools endpoint is accessible and accepts arbitrary URLs. Monitor server logs for unusual outbound HTTP requests from the application. Test with authenticated requests to internal or private IP addresses.

Impact Analysis

An attacker with low privileges could exploit this to make the backend server act as a network pivot. This enables probing internal network services, accessing private endpoints, or interacting with cloud metadata services. The backend performs these requests instead of the frontend, bypassing client-side restrictions.

Compliance Impact

This vulnerability, an authenticated Server-Side Request Forgery (SSRF) in sdcb chats, could potentially violate compliance with GDPR and HIPAA by enabling unauthorized access to internal services or sensitive data. SSRF allows attackers to probe internal networks, access private endpoints, or interact with cloud metadata services, which may expose personal or protected health information. This could lead to data breaches or unauthorized data exfiltration, directly conflicting with GDPR's data protection requirements and HIPAA's safeguards for protected health information.

Mitigation Strategies

Immediately restrict access to the POST /api/mcp/fetch-tools endpoint to authorized users only. Implement allowlists for URLs that the endpoint can access. Update sdcb chats to the latest version if a patch is available. Monitor network traffic for suspicious outbound requests.
