In Apache NiFi before 0.7.2 and 1.x before 1.1.2 in a cluster environment, the proxy chain serialization/deserialization is vulnerable to an injection attack where a carefully crafted username could impersonate another user and gain their permissions on a replicated request to another node.
Weakness
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
