SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the critical risk of cross-tenant data leakage and unauthorized function invocation in multi-tenant applications by providing a structured, safe, and repeatable validation framework.

Core Features & Use Cases

  • Boundary Mapping: Systematically identifies how tenant context is established and which resources are scoped to specific tenants.
  • Cross-Tenant Probing: Executes controlled tests to verify that Tenant-A cannot access, modify, or observe Tenant-B data or side-channel signals.
  • Use Case: During a security assessment of a SaaS platform, use this skill to confirm that API endpoints correctly enforce tenant isolation and that no cross-tenant side-channel leaks exist in search or reporting features.

Quick Start

Use the access-tenant-isolation skill to initiate a boundary validation test between two authorized test tenants defined in the current scope.

FAQPage Schema
How do I test for cross-tenant data access vulnerabilities in a multi-tenant SaaS application?▼

Multi-tenant isolation validation involves mapping tenant boundaries and executing controlled cross-tenant probes to verify Tenant-A cannot access, modify, or observe Tenant-B data. It systematically tests SaaS applications and cloud infrastructure to confirm strict tenant scoping and prevent unauthorized data leakage.

How do I perform a cross-tenant function invocation test during a pentest?▼

Perform cross-tenant function invocation testing by probing API endpoints with credentials from one tenant to attempt actions scoped to another. This validates that access controls correctly block unauthorized execution across tenant boundaries and prevent cross-tenant side-channel leaks.

What is the best way to check for side-channel leaks in multi-tenant API architectures?▼

The best way to check for side-channel leaks is to conduct controlled cross-tenant probing across multi-tenant API architectures. This involves observing search and reporting features to verify that Tenant-A cannot detect side-channel signals originating from Tenant-B.

Does tenant isolation testing require defined scope and authorization proofs for cloud infrastructure?▼

Yes, tenant isolation testing requires strict adherence to defined scope, explicit authorization proofs, and stop-on-sight safety protocols. These controls are mandatory to prevent unintended production impact when probing cloud infrastructure and multi-tenant SaaS boundaries.

When should I not use automated cross-tenant probing in a SaaS security assessment?▼

You should not use automated cross-tenant probing without strict adherence to defined scope and stop-on-sight safety protocols. Proceeding without explicit authorization proofs risks causing unintended production impact and violating tenant boundary safety.
