x/vulndb: potential Go vuln in github.com/openfga/openfga: CVE-2023-43645

[GoVulnBot]

CVE-2023-43645 references github.com/openfga/openfga, which may be a Go module.

Description:
OpenFGA is an authorization/permission engine built for developers and inspired by Google Zanzibar. OpenFGA is vulnerable to a denial of service attack when certain Check calls are executed against authorization models that contain circular relationship definitions. When the call is made, it's possible for the server to exhaust resources and die. Users are advised to upgrade to v1.3.2 and update any offending models. There are no known workarounds for this vulnerability. Note that for models which contained cycles or a relation definition that has the relation itself in its evaluation path, checks and queries that require evaluation will no longer be evaluated on v1.3.2+ and will return errors instead. Users who do not have cyclic models are unaffected.

The fix is to the internal/graph package, which is imported only by pkg/server and sub-packages, and those seem to be imported only by the command.

So vulnerability in tool.
