Security Misconfiguration in Chi with Cockroachdb

Security misconfiguration in a Chi application using CockroachDB often arises from default settings, overly permissive network rules, or improper handling of database credentials. When a Chi service connects to CockroachDB without enforcing strict transport security or schema-level authorization, it can expose sensitive data paths or allow unauthorized query execution. For example, binding the database listener to all interfaces (0.0.0.0) instead of localhost or a private subnet makes the instance reachable from outside the trusted network.

Another common misconfiguration is failing to enforce role-based access controls (RBAC) within CockroachDB, leading to accounts with unnecessary privileges. If the Chi application uses a single high-privilege database user for all operations, a compromised component can perform destructive actions such as dropping tables or exfiltrating records. Additionally, missing or incorrect TLS settings allow cleartext traffic between Chi and CockroachDB, risking credential interception and query tampering.

Insecure connection strings stored in environment variables or configuration files further compound the issue. Should these artifacts be exposed in logs or error messages, an attacker can gain direct access to the CockroachDB cluster. The interplay between Chi’s routing logic and CockroachDB’s authentication mechanisms means that weak session handling or absent request validation can turn a simple misconfiguration into a data exposure incident.

middleBrick scans such unauthenticated attack surfaces and identifies these misconfigurations by correlating OpenAPI specifications with runtime behavior. For instance, if an endpoint constructs dynamic queries without input validation and the database lacks row-level security, the scan highlights the risk of unauthorized data access. This detection helps teams address issues specific to Chi and CockroachDB before they are exploited in the wild.

Remediation begins with tightening network and transport settings. Ensure CockroachDB listens only on internal interfaces and that Chi connects via encrypted channels. Use certificate-based authentication and enforce TLS for all connections.

// cockroachdb-secure-config.ts
export const cockroachConfig = {
  host: 'private-internal-host.cockroachdb.svc.cluster.local',
  port: 26257,
  ssl: {
    rejectUnauthorized: true,
    ca: fs.readFileSync('/path/to/ca.crt').toString(),
    key: fs.readFileSync('/path/to/client.key').toString(),
    cert: fs.readFileSync('/path/to/client.crt').toString(),
  },
};

Define granular roles in CockroachDB and map Chi service accounts to least-privilege permissions. Avoid using the root user in application code.

-- Create a dedicated role for Chi read-write operations on orders
CREATE ROLE chi_orders_rw;
GRANT SELECT, INSERT, UPDATE ON DATABASE mydb TO chi_orders_rw;
GRANT USAGE ON SCHEMA public TO chi_orders_rw;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT, INSERT, UPDATE ON TABLES TO chi_orders_rw;

-- Bind Chi application user to this role
CREATE USER chi_app WITH PASSWORD 'strong-password';
GRANT chi_orders_rw TO chi_app;

In Chi, parameterize queries and validate inputs to prevent injection and malformed requests. Use environment-managed secrets for connection strings and rotate credentials regularly.

// chi-db-client.ts
import { Pool } from 'pg';
import { cockroachConfig } from './cockroachdb-secure-config';

const pool = new Pool({
  connectionString: process.env.COCKROACH_URI,
  ssl: cockroachConfig.ssl,
  application_name: 'chi-service',
});

export const getUserOrders = async (userId: string) => {
  const client = await pool.connect();
  try {
    const result = await client.query(
      'SELECT id, total, status FROM orders WHERE user_id = $1',
      [userId]
    );
    return result.rows;
  } finally {
    client.release();
  }
};

Leverage middleBrick’s CLI to validate these configurations in your pipeline. The scan checks for weak authentication, missing encryption, and excessive privileges, providing prioritized findings with remediation guidance. For teams using the Pro plan, continuous monitoring ensures configuration drift is caught early, while the GitHub Action can fail builds if risk thresholds are exceeded.
