Updated

In multi-tenant deployments, the Publisher REST APIs fail to enforce tenant isolation correctly. This allows a user in one tenant, possessing sufficient privileges to invoke these APIs, to perform operations that impact other tenants.

The vulnerability allows a privileged user to perform publisher operations such as exposing or modifying API Metadata in another tenant environment. This impact is only realized in multi-tenant deployments.
