🔒 Critical Security Fix: Cross-Tenant Data Leakage Prevention (Issue #1)
[CRITICAL SECURITY] Implement Tenant Isolation to Prevent Cross-Tenant Data Leakage
📝 Issue Description
🚨 The Problem
LeadOrbit is a multi-tenant application that currently suffers from a critical security vulnerability. The README explicitly acknowledges:
"analytics currently uses unscoped aggregate queries, and a few utility endpoints are intentionally permissive."
This means:
Data Leakage Risk: A user from Organization A can potentially access or deduce sensitive data from Organization B by manipulating API parameters.
Missing Security Layer: There's no mandatory tenant filtering at the database level.
No Authorization Check: The system doesn't verify if a user has permission to access data from their organization.
Scaling Nightmare: As the platform grows, this vulnerability becomes more dangerous and harder to fix.
💥 Potential Impact
Confidentiality Breach: Leaked email addresses, campaign strategies, lead information
Competitive Intelligence: Users could see competitors' outreach metrics
Legal Liability: GDPR, CCPA, and other data protection violations
Trust Erosion: Organizations would lose trust in the platform
🎯 The Solution
Implement a comprehensive tenant isolation layer that enforces mandatory data separation:
- Tenant-Aware Base Model
Create an abstract base class that all models will inherit from:
Adds tenant foreign key to every model
Overrides the default manager to automatically filter by current tenant
Ensures no query can accidentally access cross-tenant data
- Tenant Middleware
Create a middleware that:
Extracts the current user from JWT token
Identifies their organization
Stores the tenant ID in thread-local storage for the entire request lifecycle
Prevents any request from processing without a valid tenant context
- Model Migrations
Add tenant field to all existing models
Create data migration to assign existing records to appropriate tenants
Add database indexes for performance
