Attack-Flow Graph

Executive Summary

This vulnerability is a server-side request forgery (SSRF) in the cowork_bench project's pdf-tools-mcp component. It exists in the ControlFlowNode function of the server.py file where manipulating the pdf_file_path argument allows an attacker to forge requests to internal or external servers. The exploit is publicly available and can be triggered remotely.

Impact Analysis

This SSRF vulnerability could allow attackers to access internal services, exfiltrate data, or make unauthorized requests on behalf of the server. If you use this software, attackers might exploit it to interact with internal systems or sensitive resources, potentially leading to data breaches or service disruption.

Compliance Impact

This vulnerability could lead to unauthorized data access or exfiltration, violating GDPR's data protection principles or HIPAA's security requirements for protected health information. Compliance may be compromised if sensitive data is exposed due to this SSRF flaw.

Mitigation Strategies

Immediately disable or restrict access to the pdf-tools-mcp component in cowork_bench. Review and filter network traffic to prevent server-side request forgery attempts targeting the pdf_file_path argument. Monitor for unusual outbound requests from the affected system.
