Executive Summary

This is a Server-Side Request Forgery (SSRF) vulnerability in the poco-ai poco-claw software up to version 0.5.4. It exists in the run_task function of executor/app/api/v1/task.py where the callback_url parameter is manipulated to make unauthorized server-side HTTP requests to arbitrary destinations without validation. This includes internal systems or loopback addresses.

Detection Guidance

Check if your system runs poco-ai poco-claw up to 0.5.4. Monitor network traffic for unexpected outbound requests to internal or external addresses from the executor component. Inspect logs for POST requests to /v1/tasks/execute with callback_url parameters pointing to unusual destinations.

Impact Analysis

An attacker could exploit this to probe internal systems, access cloud metadata endpoints if reachable, or receive sensitive data from the executor such as task metadata and agent status messages. The impact includes unauthorized access to internal resources and potential data exfiltration.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, which may violate data protection requirements under GDPR or HIPAA. Exposure of internal systems or metadata could result in non-compliance with these regulations due to potential data breaches or unauthorized disclosure.

Mitigation Strategies

Upgrade to a patched version if available. If no patch exists, disable the POST /v1/tasks/execute endpoint or restrict access via network policies. Implement strict validation for callback_url parameters to allow only trusted domains.
