The latest version of the docker image is v1.18.3. It's a little tricky, this package, gobuffalo/buffalo, is the core library for the buffalo apps while the separated package gobuffalo/cli provides buffalo cli. The docker image follows the version of the buffalo cli since the image is basically for development.

To add to what @sio4 said:

The reason that the newest docker image is versioned according to the CLI at version v0.18.3 is because that's the only thing that is included in the image. The gobuffalo/buffalo library isn't included in the docker image, it is referenced by your go.mod file and is fetched during the build process.

So if you want to use the newest gobuffalo/buffalo library you can just call:

go get github.com/gobuffalo/buffalo
go mod tidy       # optional to remove unneeded dependencies from your go.mod and go.sum files

and commit the changes to your repository.
