Beast Attack in Adonisjs with Cockroachdb

A Beast Attack (a variant of Insecure Direct Object Reference / BOLA) in Adonisjs with Cockroachdb occurs when an application exposes internal record identifiers (e.g., primary keys or UUIDs) in URLs or API endpoints and uses them to directly fetch domain models without verifying that the requesting user is authorized to access the specific resource. With Cockroachdb as the backing store, this often surfaces when query scopes or row-level protections are not consistently applied, allowing an attacker to iterate through valid-looking identifiers and read or modify data that belongs to other users.

Adonisjs encourages the use of Lucid models which rely on primary key lookups such as Post.findOrFail(params.id). If this call is made without scoping to the requesting user (e.g., Post.query().where('user_id', user.id)), an attacker can supply any known ID and potentially access or update records they should not see or change. Cockroachdb behaves like other SQL databases in this regard; there is no implicit tenant isolation. If your schema stores tenant or user context in columns like user_id or team_id, the database will not enforce isolation on its own. The vulnerability is therefore introduced by application code that omits these scopes or trusts client-supplied identifiers without re-confirming authorization against the database.

Additional exposure can occur when APIs return internal IDs in responses or error messages. For example, a JSON API that includes { post_id: 123 } can make it trivial for an attacker to enumerate other valid IDs. In Adonisjs, this may happen when serializing models without filtering sensitive fields or when logs capture query bindings that include record IDs. Because Cockroachdb uses a distributed SQL layer, the semantics of primary keys remain consistent, but the lack of strict application-level checks means an attacker can probe sequential or predictable IDs across nodes and observe differences in responses (existence, data content, or timing) to infer access rights.

Real-world attack patterns include changing numeric IDs in REST routes (e.g., PATCH /posts/12345) or tampering with opaque identifiers in GraphQL payloads. If Adonisjs routes rely on route parameters bound directly to model queries, and those queries do not incorporate the authenticated user context, the unauthenticated or low-privilege attacker can read, update, or delete records. OWASP API Top 10 categorizes this as Broken Object Level Authorization (BOLA), and PCI-DSS, SOC2, HIPAA, and GDPR all expect controls that prevent unauthorized access to data by reference to user-supplied identifiers.

To detect this with middleBrick, which supports OpenAPI/Swagger spec analysis and runtime checks, you would submit your API URL to the scanner. The tool runs 12 security checks in parallel, including BOLA/IDOR, and maps findings to frameworks such as OWASP API Top 10. Its LLM/AI Security module can also probe for system prompt leakage or output exposure that might indirectly aid enumeration, while the dashboard lets you track scores and prioritize remediation.

Remediation focuses on ensuring every data access is scoped to the requesting user or tenant and that internal IDs are never assumed to be safe. In Adonisjs, prefer route-level or controller-level scoping so that queries always filter by user_id or team_id. Avoid using findOrFail(params.id) in isolation; instead, build constrained queries that the database can enforce.

Example: Scoped Post retrieval with Cockroachdb

import Post from '#models/post'
import type HttpContext from '@ioc:Adonis/Core/HttpContext'

export default class PostsController {
  async show({ params, auth }: HttpContext) {
    const user = await auth.authenticate()
    const post = await Post.query()
      .where('user_id', user.id)
      .andWhere('id', params.id)
      .preload('comments')
      .firstOrFail()
    return post
  }
}

This pattern ensures that even if an attacker guesses or iterates over IDs, the Cockroachdb query will return empty when the id does not belong to the authenticated user_id, causing firstOrFail to throw a 404. The same principle applies to updates and deletes.

Example: Scoped update with explicit ownership check

import Post from '#models/post'

export async function updatePost(context, postId: number) {
  const { auth, request } = context
  const user = await auth.authenticate()
  const payload = request.only(['title', 'content'])

  const post = await Post.query()
    .where('user_id', user.id)
    .andWhere('id', postId)
    .update(payload)

  if (!post) {
    // handle not found or not authorized
    throw new Error('Post not found or access denied')
  }
  return post
}

When using Cockroachdb, ensure your schema enforces uniqueness and constraints at the database level (e.g., unique composite indexes on (user_id, id) where appropriate), but do not rely on the database to enforce authorization. Application logic must still perform checks because business rules often include multi-tenant or role-based conditions beyond simple ownership.

Example: Safe creation that binds the tenant

import Post from '#models/post'

export async function createPost(context) {
  const { auth, request } = context
  const user = await auth.authenticate()
  const data = request.only(['title', 'content'])

  const post = await Post.create({
    ...data,
    userId: user.id,
  })
  return post
}

For composite keys or UUID primary keys, continue to scope by tenant identifiers. If you use UUIDs, ensure they are not guessable, but still pair them with tenant or user columns in WHERE clauses. middleBrick’s CLI tool (middlebrick scan <url>) can validate that endpoints consistently apply such scoping by inspecting request flows and detecting missing authorization checks.

General practices

• Always include tenant or user filters in Lucid queries that read or modify records.
• Do not expose raw database IDs in URLs when tenant isolation is required; consider opaque identifiers mapped server-side to internal keys.
• Apply consistent route-level scoping or global query hooks in Adonisjs to avoid accidentally omitting filters.
• Use middleBrick’s GitHub Action to fail CI/CD builds if new endpoints lack required authorization scopes, and leverage the Pro plan’s continuous monitoring to detect regressions over time.
