Executive Summary

CVE-2026-16127 is a Server-Side Request Forgery (SSRF) vulnerability in the zevorn rt-claw tool up to version 0.2.0. The issue occurs in the http_request component where user-supplied URLs are passed to claw_net_get or claw_net_post without proper validation. This allows attackers to manipulate the URL parameter to access internal or private network resources, including loopback addresses like 127.0.0.1.

Detection Guidance

Check if rt-claw versions up to 0.2.0 are installed. Monitor network traffic for unexpected outbound requests to loopback or private IPs from the rt-claw process. Inspect logs for claw_net_get or claw_net_post function calls with user-supplied URLs.

Impact Analysis

This vulnerability allows attackers to access sensitive data from internal HTTP services on your device or network. They could retrieve secrets, perform port scans, or interact with internal systems by sending crafted messages through supported channels like Telegram or Feishu integrations. The exploit is publicly available and can be executed remotely.

Compliance Impact

This SSRF vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection principles and HIPAA's security requirements for protected health information. Unauthorized data exposure may result in non-compliance, legal penalties, and reputational damage due to insufficient network access controls.

Mitigation Strategies

Upgrade rt-claw to a patched version if available. Implement SSRF protections like allowlisting or blocklisting for URLs. Restrict network access for the rt-claw process to prevent outbound connections to sensitive endpoints.
