Description

Capgo before 12.128.2 contains a broken object level authorization vulnerability in middlewareKey() that accepts the client-controlled x-limited-key-id header without validating ownership, allowing authenticated users to adopt cross-tenant limited keys. Attackers can supply another tenant's limited key ID to bypass authorization checks and access unauthorized cross-tenant resources across multiple API endpoints.
