CVE-2026-7061 Overview
A command injection vulnerability has been identified in Toowiredd chatgpt-mcp-server versions up to 0.1.0. The vulnerability exists in the file src/services/docker.service.ts within the MCP/HTTP component. This flaw allows attackers to inject arbitrary operating system commands through manipulation of the affected functionality, potentially leading to unauthorized command execution on the target system.
Critical Impact
Remote attackers can exploit this OS command injection vulnerability to execute arbitrary commands on the underlying system, potentially compromising confidentiality, integrity, and availability of the affected server.
Affected Products
- Toowiredd chatgpt-mcp-server version 0.1.0 and earlier
- Systems running the MCP/HTTP component with exposed Docker service functionality

Technical Details for CVE-2026-7061
Vulnerability Analysis
This vulnerability is classified as CWE-77 (Improper Neutralization of Special Elements used in a Command - Command Injection). The flaw exists in the Docker service implementation within the chatgpt-mcp-server application, specifically in the docker.service.ts file that handles MCP/HTTP requests.
The vulnerability allows attackers to inject malicious commands that are subsequently executed by the underlying operating system. Given the network-accessible attack vector, remote exploitation is possible without requiring any authentication or user interaction, making this a significant security concern for exposed instances.
The exploit has been made publicly available, increasing the risk of active exploitation. According to the GitHub Issue Tracker, the project maintainers were notified of this vulnerability but had not responded at the time of disclosure.
Root Cause
The root cause of this vulnerability is insufficient input validation and sanitization in the Docker service component. When processing requests through the MCP/HTTP interface, user-supplied input is passed to system commands without proper escaping or filtering of shell metacharacters. This allows specially crafted input containing command separators (such as ;, |, &&, or backticks) to break out of the intended command context and execute arbitrary commands.
Attack Vector
The vulnerability is exploitable remotely over the network. An attacker can craft malicious HTTP requests to the MCP interface that include command injection payloads. These payloads are processed by the docker.service.ts component and executed with the privileges of the application process.
The attack does not require authentication or any special privileges, and no user interaction is needed for successful exploitation. Attackers can leverage this vulnerability to:
- Execute arbitrary system commands
- Read or modify sensitive files
- Establish persistent access to the compromised system
- Pivot to other systems on the network
Technical details and proof-of-concept information can be found in the VulDB Vulnerability Detail and the related public exploit repository.
Detection Methods for CVE-2026-7061
Indicators of Compromise
- Unusual HTTP requests to the MCP/HTTP endpoints containing shell metacharacters (;, |, &&, ||, backticks, $())
- Unexpected child processes spawned by the chatgpt-mcp-server application
- Anomalous outbound network connections from the server hosting the vulnerable application
- Suspicious entries in application logs showing command injection patterns
Detection Strategies
- Implement web application firewall (WAF) rules to detect and block requests containing common command injection payloads
- Monitor process trees for unexpected child processes spawned by Node.js or the chatgpt-mcp-server application
- Deploy endpoint detection and response (EDR) solutions to identify suspicious command execution patterns
- Review application logs for HTTP requests with unusual parameters containing shell special characters
Monitoring Recommendations
- Enable detailed logging for all MCP/HTTP endpoint requests and responses
- Set up alerts for process creation events originating from the chatgpt-mcp-server application
- Monitor network traffic for unusual outbound connections from the application server
- Implement file integrity monitoring on critical system directories
How to Mitigate CVE-2026-7061
Immediate Actions Required
- Restrict network access to the chatgpt-mcp-server MCP/HTTP endpoints to trusted sources only
- Implement firewall rules to limit exposure of the vulnerable service
- Consider temporarily disabling the Docker service functionality if not required
- Deploy a web application firewall with command injection detection rules in front of the application
Patch Information
At the time of this writing, no official patch has been released by the vendor. The project maintainers were notified through an issue report but have not yet responded. Users should monitor the project repository for security updates and apply patches as soon as they become available.
Workarounds
- Place the chatgpt-mcp-server behind a reverse proxy that sanitizes and validates all incoming requests
- Implement network segmentation to isolate the vulnerable application from critical infrastructure
- Use container security solutions to restrict the capabilities of the application process
- Apply the principle of least privilege to the service account running the application
# Example: Restrict access to MCP endpoints using iptables
# Allow only trusted IP addresses to access the service port
iptables -A INPUT -p tcp --dport 3000 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 3000 -j DROP
