CVE-2024-23820: OpenFGA denial of service

Overview

OpenFGA is vulnerable to a DoS attack. In some scenarios that depend on the model and tuples used, a call to ListObjects may not release memory properly. So when a sufficiently high number of those calls are executed, the OpenFGA server can create an "out of memory" error and terminate.

Fix

Upgrade to v1.4.3. This upgrade is backwards compatible.

Root Cause Analysis

The vulnerability stems from improper resource cleanup in ListObjects handling. The commit fixes show critical changes to channel management patterns:

In list_objects.go, the consumer loop was restructured to handle channel closure properly and added error channel separation
In reverse_expand.go, the Execute function was modified to return errors directly instead of sending through the channel, ensuring proper cleanup
The removal of ReverseExpandResult.Err field indicates a shift in error handling strategy These changes address CWE-401 (memory not released) by ensuring channels are closed and goroutines properly terminated, and CWE-770 (resource limits) through better concurrency control.
