You can enforce tenant access by applying the CheckTenantAccess middleware to routes using auth:sanctum with shared prefixes like /admin/api/v1 and /api/v1, ensuring cross-tenant leakage is prevented while keeping account-only routes unaffected.

CheckTenantAccess is a middleware mechanism used in Laravel multi-tenant applications to enforce tenant access governance on authenticated routes, preventing unauthorized cross-tenant data leakage by verifying tenant boundaries on routes secured with auth:sanctum.

To prevent cross-tenant data leakage in Laravel API routes, enforce the CheckTenantAccess middleware on all tenant-authenticated routes using auth:sanctum and add corresponding tests to verify that cross-tenant access scenarios are properly blocked.

No, CheckTenantAccess does not affect account-only routes in Laravel. It specifically targets tenant-authenticated routes with shared prefixes, keeping account-only routes separate and unaffected while enforcing guardrails only where tenant boundaries apply.

To test tenant access guardrails in Laravel Sanctum routes, audit your route definitions to verify CheckTenantAccess is present and update your test suite to cover cross-tenant access scenarios, referencing the tenant-access-guardrails workflow documentation.
