@objectstack/plugin-security

Security Plugin for ObjectStack — RBAC, Row-Level Security (RLS), and Field-Level Security runtime.

Features

• RBAC Permission Evaluator: Checks object-level CRUD permissions per user role with most-permissive merging across multiple roles.
• Row-Level Security (RLS): Compiles RLS policy expressions into ObjectQL query filters, automatically injected into all read operations.
• Field-Level Masking: Strips non-readable fields from query results and identifies non-editable fields.
• ObjectQL Middleware Integration: Hooks into the ObjectQL pipeline to enforce security transparently on every operation.
• System Bypass: System-level operations skip security checks for internal workflows.

Usage

import { SecurityPlugin } from '@objectstack/plugin-security';
import { ObjectKernel } from '@objectstack/core';

const kernel = new ObjectKernel({
  plugins: [
    new SecurityPlugin(),
  ],
});

Exported Components

import {
  SecurityPlugin,
  PermissionEvaluator,
  RLSCompiler,
  FieldMasker,
} from '@objectstack/plugin-security';

Architecture

The plugin registers three core services and executes a 4-step security chain on every data operation:

1. Resolve Permission Sets — Match user roles to permission set definitions from metadata.
2. Check Object Permissions — Validate CRUD access (allowRead, allowCreate, allowEdit, allowDelete).
3. Inject RLS Filters — Compile row-level policy expressions and merge them into the query.
4. Mask Fields — Remove restricted fields from results based on field-level permissions.
