The cloudfoundry-community github org is open to anyone in the community who'd like to publicize their code. I don't believe there are any strict guidelines around the license that should be applied; and in fact this code is explicitly **not** owned by the CF Foundation.
Instead, this code is owned by its authors and contributors. I'd suggest that you open a Github Issue on the repo asking for a license to be explicilty declared, either in the README or in a separate LICENSE file. Usually authors are very willing to do so once asked.
