Read-only configuration override via verification requests
Published Jun 22, 2026 · Updated Jun 22, 2026
Incorrect authorization in Apache NiFi 1.15.0 through 2.9.0 allows remote authenticated users with read access to verify altered settings. Configuration-verification REST methods accept proposed component properties that replace current values for predefined verification without requiring component write authorization. Only deployments that separate read and write component permissions are exposed; read-only users can invoke verification logic with alternative configuration.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
