The patched file that fixes this https://go-review.googlesource.com/c/go/+/699275/3/src/net/http/csrf.go isn't included anywhere in the buildah sources built for Fedora.

Did you mean "go sources built for Fedora 42"?

This doesn't affect anything older than Go 1.25.0:
https://pkg.go.dev/vuln/GO-2025-3955

... Fedora 42 only has Go 1.24.7:
