Source Advisory Statement

## Overview OpenFGA is vulnerable to a DoS attack. When a number of ListObjects calls are executed, in some scenarios, those calls are not releasing resources even after a response has been sent, and the service as a whole becomes unresponsive. ## Fix Upgrade to v1.3.4. This upgrade is backwards compatible.
