Attack-Flow Graph

Executive Summary

This vulnerability is a server-side request forgery (SSRF) in graphlit graphlit-mcp-server 1.0.1. It exists in the fetch function of src/tools.ts, specifically in the ssrf-test endpoint. An attacker can manipulate the url argument to force the server to make unauthorized requests. The exploit is publicly available and the vendor has not responded to the reported issue.

Detection Guidance

This vulnerability involves a server-side request forgery (SSRF) in the graphlit-mcp-server 1.0.1 due to improper handling of the 'url' argument in the ssrf-test endpoint. To detect it, monitor network traffic for unexpected outbound requests from the server, especially to internal or sensitive resources. Check server logs for unusual URL parsing or access attempts. Use tools like curl to test the endpoint manually by sending crafted requests to the vulnerable function.

Impact Analysis

This SSRF vulnerability may allow remote attackers to access internal systems or sensitive data through the affected server. It could lead to unauthorized network scanning, data exfiltration, or further attacks on internal infrastructure. The impact depends on the server's network configuration and permissions.

Compliance Impact

The vulnerability is a server-side request forgery (SSRF) issue in graphlit-mcp-server 1.0.1, allowing remote manipulation of URL arguments. This could potentially expose sensitive data or internal systems, which may impact compliance with GDPR (data protection) or HIPAA (healthcare data privacy) if exploited.

Mitigation Strategies

Immediately disable or restrict access to the ssrf-test endpoint in graphlit-mcp-server 1.0.1. Update to a patched version if available. Monitor network traffic for unusual outbound requests from the server.
