Description
Found a possible issue in [system-dev-formations/k8s-webforce3](https://www.github.com/system-dev-formations/k8s-webforce3) at [cnat/cnat-operator/vendor/k8s.io/kube-openapi/pkg/aggregator/aggregator.go](https://github.com/system-dev-formations/k8s-webforce3/blob/3d8a6e826b40c03c4a374b5143df5dd8bb38d49c/cnat/cnat-operator/vendor/k8s.io/kube-openapi/pkg/aggregator/aggregator.go#L78-L81)
Below is the message reported by the analyzer for this snippet of code. Beware that the analyzer only reports the first issue it finds, so please do not limit your consideration to the contents of the below message.
> function call at line 79 may store a reference to v

Click here to show the 4 line(s) of Go which triggered the analyzer.
```go
for k, v := range schema.Definitions {
s.walkSchema(&v)
schema.Definitions[k] = v
}
```
Click here to show extra information the analyzer produced.
```
The following graphviz dot graph describes paths through the callgraph that could lead to a function which writes a pointer argument:
digraph G {
"(walkSchema, 1)" -> {}
}
No path was found through the callgraph that could lead to a function which passes a pointer to third-party code.
```

Research direction
Read cnat/cnat-operator/vendor/k8s.io/kube-openapi/pkg/aggregator/aggregator.go around lines 78-81, then inspect walkSchema to determine whether the range variable reference can be retained or modified. Compare the analyzer warning with the surrounding schema aggregation logic; done means classifying the finding as Bug, Mitigated, or Desirable Behavior.
