Apache NiFi是美国Apache基金会开源的一款支持数据流转与处理的消息队列中间件。 Apache NiFi 1.10.0版本至2.10.0版本存在授权问题漏洞，该漏洞源于参数上下文验证请求的授权处理不当，可能允许具有读取权限的客户端提交建议的参数值，覆盖当前配置，从而以替代设置调用预定义的组件验证方法。

Vulnerability Title
Apache NiFi: Incorrect Authorization for Parameter Context Validation Requests
Source: CVE Program / CVE List V5
Vulnerability Description
Authorization handling for Parameter Context validation requests in Apache NiFi 1.10.0 through 2.10.0 allows clients with read access to submit proposed Parameter values. The proposed values override current configuration, enabling users with read access to invoke predefined component validation methods with alternative settings. Apache NiFi installations that do not implement different levels of authorization for viewing and modifying Parameter Context configuration are not subject to this vulnerability. Upgrading to Apache NiFi 2.11.0 is the recommended mitigation, requiring write access to submit Parameter Context validation requests.
