Was 6.6.15.1 Removed from Docker Hub as a Tag?

[Josh]

Hi all -

Running into an odd issue here. After https://apereo.github.io/2024/05/18/oauth-vuln/ was released, we upgrade our nodes to 6.6.15.1. We're pushing this same logic to a new set of nodes and are receiving the following error:

Unable to find image 'apereo/cas:6.6.15.1' locally
docker: Error response from daemon: manifest for apereo/cas:6.6.15.1 not found: manifest unknown: manifest unknown.

It looks like the tagged release for 6.6.15.1 has vanished as a tag for apereo/cas in https://hub.docker.com/r/apereo/cas/tags. It was definitely there on or around 5/18 though when we patched our production nodes.

Any help would be greatly appreciated as we need to push v6.6 to a few new nodes but do not want to run on a vulnerable version.
