Versions of Pulp < 2.3.0 distributed the same certificate authority key and
certificate to all Pulp users. This CA is used by the /login API call
(pulp-admin login uses this call) to generate and sign a client certificate.
This client certificate is then used for subsequent API calls.
Due to this vulnerability, remote attackers are able to obtain the CA key
from the Pulp git repository and use it to generate valid client certificates
for any Pulp installations that use the default CA. The Pulp documentation
did not emphasize the importance of replacing this CA for production
deployments, so there may be users who use this common CA key in production
