Overview

org.apache.nifi:nifi-web-security

Affected versions of this package are vulnerable to User Impersonation. An attacker could carefully craft a username to impersonate another user and gain their permissions on a replicated request to another node, via the the proxy chain serialization/deserialization functions as they are vulnerable to an injection attack. This only occurs in a cluster environment.
