Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Ranger's ranger-nifi-registry-plugin package, versions before 2.8.0, does not properly verify host names on certificates in its NiFiRegistryClient and NiFiClient components. The source gives few details about how an attacker would exploit this or what access they need. Users should upgrade to version 2.8.0, which fixes the issue.
