Severity: Important

Versions Affected:

Apache NiFi 0.0.1 - 0.7.3

Description: Apache NiFi needs to establish the response header telling
browsers to only allow framing with the same origin.

Severity: Important

Versions Affected:

Apache NiFi 0.0.1 - 0.7.3
Apache NiFi 1.0.0 - 1.2.0

a prior 0.x or 1.x release should upgrade to the appropriate release.
