Executive Summary

This vulnerability is a command injection flaw in the NightTrek Supabase-MCP tool. The generate_types component improperly handles user-controlled input in the schema argument, directly embedding it into shell commands without validation or escaping. This allows attackers to inject malicious shell commands, potentially executing arbitrary code on the host system running the MCP server.

Detection Guidance

To detect this vulnerability, check if the NightTrek Supabase-MCP server is running version 0.1.0 or if the generate_types tool is exposed. Inspect logs for unusual shell command patterns or unexpected command execution. Look for schema parameters containing shell metacharacters like semicolons, pipes, or command substitutions.

Impact Analysis

If exploited, this vulnerability could allow attackers to run arbitrary commands on your system with the same privileges as the MCP server. This may lead to unauthorized access, data theft, system compromise, or further network infiltration depending on the server's permissions and environment.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR's data protection principles and HIPAA's security requirements for protected health information. Organizations may face compliance breaches, legal penalties, and reputational damage if sensitive data is compromised through this flaw.

Mitigation Strategies

Immediately update the Supabase-MCP server to a patched version that avoids shell command concatenation. If updating is not possible, disable the generate_types tool or restrict access to trusted users only. Rotate the service_role key if exposed and review all configurations for credential leaks.
