CVE-2018-17192: Apache Nifi

Medium severity, CVSS 6.5. EPSS: 2.7% chance of exploitation in the next 30 days.

The X-Frame-Options headers were applied inconsistently on some HTTP responses, resulting in duplicate or missing security headers. Some browsers would interpret these results incorrectly, allowing clickjacking attacks. Mitigation: The fix to consistently apply the security headers was applied on the Apache NiFi 1.8.0 release. Users running a prior 1.x release should upgrade to the appropriate release.

Affected products

• Apache Nifi: from 1.0.0, up to and including 1.6.0
