A flaw was found in Ansible Galaxy Collections. When collections are built manually, any files in the repository directory that are not explicitly excluded via the ``build_ignore`` list in "galaxy.yml" include files in the ``.tar.gz`` file. This contains sensitive info, such as the user's Ansible Galaxy API key and any secrets in ``ansible`` or ``ansible-playbook`` verbose output without the``no_log`` redaction. Currently, there is no way to deprecate a Collection Or delete a Collection Version. Once published, anyone who downloads or installs the collection can view the secrets.
