Security Misconfiguration in Adonisjs with Cockroachdb

Security misconfiguration in an AdonisJS application using CockroachDB often arises from mismatched settings between the ORM/query layer and the database cluster’s security posture. When connection pooling, SSL enforcement, or authentication mechanisms are not explicitly defined, the application may fall back to weaker defaults or expose internal endpoints.

AdonisJS relies on @ioc:AdonisJS/Lucid for database access, and with CockroachDB the config/database.ts file defines connection parameters. Common misconfigurations include:

• Disabling SSL (ssl: false) while connecting to a CockroachDB cluster that requires TLS, enabling eavesdropping on internal traffic.
• Overly permissive database user privileges assigned in CockroachDB SQL (e.g., GRANT ALL ON DATABASE appdb TO appuser) without scoped roles, allowing broader impact if credentials leak.
• Hardcoded or environment-variable–exposed credentials in .env without restricting file permissions, enabling unauthorized database access via server compromise.
• Improper connection string formatting for multi-node CockroachDB clusters, omitting certificate authorities or using non-routable internal addresses that bypass intended network segmentation.

These issues intersect with the 12 security checks in middleBrick. For example, Input Validation failures can occur if user input is directly interpolated into dynamic queries without parameterization, while BOLA/IDOR may surface when row-level security is not enforced at the database level. middleBrick’s scan would flag these findings with severity and remediation guidance, and the OpenAPI/Swagger spec analysis (with full $ref resolution) can highlight mismatched auth schemes between spec and runtime behavior.

In a CI/CD context, the middleBrick GitHub Action can be added to fail builds if the risk score drops below your threshold, preventing misconfigured AdonisJS + Cockroachdb deployments from reaching production. The CLI tool (middlebrick scan <url>) provides a quick, no-setup check of the unauthenticated attack surface.

Remediation focuses on aligning AdonisJS configuration with CockroachDB best practices, emphasizing encryption, least privilege, and secure connection handling.

1. Enforce SSL/TLS for all connections

Ensure your database.ts config uses SSL mode require and references the correct CA certificate. For CockroachDB, this prevents plaintext transmission even within data centers.

// config/database.ts
import { DbConfig } from '@ioc:AdonisJS/Lucid'

const dbConfig: DbConfig = {
  connection: 'cockroachdb',
  connections: {
    cockroachdb: {
      client: 'cockroachdb',
      connection: {
        host: process.env.DB_HOST || 'localhost',
        port: parseInt(process.env.DB_PORT || '26257'),
        user: process.env.DB_USER,
        password: process.env.DB_PASSWORD,
        database: process.env.DB_NAME,
        ssl: {
          rejectUnauthorized: true,
          ca: process.env.COCKRACKDB_CA_CERT // PEM string of CA
        }
      },
      debug: false
    }
  }
}

export default dbConfig

2. Apply least-privilege database roles

In CockroachDB, create a dedicated role with minimal required privileges instead of using the root or a highly privileged user.

-- CockroachDB SQL (run via cockroach sql or admin UI)
CREATE ROLE app_readwrite;
GRANT SELECT, INSERT, UPDATE, DELETE ON TABLE customers TO app_readwrite;
GRANT USAGE, SELECT ON ALL SEQUENCES IN SCHEMA public TO app_readwrite;

CREATE USER appuser WITH PASSWORD '${APPUSER_PASSWORD}';
GRANT app_readwrite TO appuser;

Then ensure AdonisJS connects with appuser and the corresponding password in environment variables.

3. Secure connection strings and environment handling

Use strongly scoped environment variables and file permissions. Avoid concatenating connection strings with user input. For multi-node clusters, include all node hostnames and the CA cert.

// .env (restrict file mode to 600)
DB_HOST=cockroach-node1.internal,cockroach-node2.internal,cockroach-node3.internal
DB_PORT=26257
DB_USER=appuser
DB_PASSWORD=super_secret_password
DB_NAME=appdb
COCKRACKDB_CA_CERT=-----BEGIN CERTIFICATE-----
MIIC... (full CA PEM)
-----END CERTIFICATE-----

middleBrick’s scan will surface unauthenticated endpoints and configuration risks; pairing it with the MCP Server allows scanning APIs directly from your AI coding assistant during development to catch misconfigurations early.
