E.g.:

$ rhsecapi --product='web server 2.1' --urls cve-2014-0231
[NOTICE ] rhsda: Found 1 CVEs on cmdline

CVE-2014-0231 (https://access.redhat.com/security/cve/CVE-2014-0231)
  SEVERITY : Moderate Impact (https://access.redhat.com/security/updates/classification)
  DATE     : 2014-07-17

This is actually a problem with CDN vs RHN -- not a problem with rhsecapi. It affects almost only MW products and I've notified the relevant people at Red Hat. (And am tracking progress.)
