Reproduce a cross-tenant RLS leak and verify the fix
Supabase RLS Leak Demo is a focused, open-source testing tool designed for developers and founders working on multi-tenant applications. It provides a simple yet powerful fixture to simulate a cross-tenant Row-Level Security (RLS) leak in PostgreSQL, allowing users to verify whether their security policies are truly effective. By running a straightforward test suite with commands like 'npm ci && npm test', users can identify potential leaks and confirm their fixesβno need for Docker, cloud credentials, or production data. This makes it an excellent resource for teams committed to security and data integrity in multi-tenant SaaS platforms. The tool's unique value lies in its ability to demonstrate that a policy may appear correct but still harbor vulnerabilities, offering clear evidence before deploying to production.
Pros
- Simple setup with zero dependencies on Docker or cloud credentials
- Open-source and easy to run locally for immediate security testing
- Provides clear, reproducible evidence of security leaks and fixes
