Upgrade org.apache.nifi:nifi-web-api to version 2.8.0 or higher.
Overview
org.apache.nifi:nifi-web-api is a system to process and distribute data.
Affected versions of this package are vulnerable to Missing Authorization when updating configuration properties on extension components with restricted permissions. An attacker can modify sensitive configuration settings by leveraging insufficient authorization checks on components that require elevated privileges.
Note:
This is only exploitable if different levels of authorization are implemented for restricted components because the framework enforces write permissions as the security boundary..
