Technical details

Two API routes (GET /api/v1/integrations/:providerConfigKey/flows and GET /api/v1/flow/:flowName) applied web authentication but omitted the required RBAC guard for reading flow resources scoped by environment. A user with development_full_access role could craft requests with ?env=prod to read production flow metadata, bypassing the production role boundary without crossing tenant isolation.

Affected products

Nango Nango before 0.70.9
