CVE-2019-10083
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedWhen updating a Process Group via the API in NiFi versions 1.3.0 to 1.9.2, the response to the request includes all of its contents (at the top most level, not recursively). The response included details about processors and controller services which the user may not have had read access to.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceIn NiFi versions 1.3.0 to 1.9.2, when updating a Process Group via the REST API, the response returns all top-level contents including details about processors and controller services. This exposes information about components that the requesting user may not have explicit read access to, creating an information disclosure vulnerability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed NiFi versionCheck the NiFi version by accessing the NiFi UI footer, or checking the nifi-version.log file in the NiFi logs directory, or running: ./nifi.sh version 2>/dev/nullAffected if The installed version is >= 1.3.0 and <= 1.9.2
-
Verify the NiFi REST API is exposedConfirm the NiFi REST API endpoint is accessible (typically on port 8080 or 8443). Test with: curl -s http://localhost:8080/nifi-api/Affected if The REST API endpoint responds and is accessible over the network
-
Check user access controls on Process GroupsReview the authorization configuration in nifi.properties and the authorizers.xml file to determine if fine-grained access controls are configured for Process GroupsAffected if Users have limited/role-based access to Process Groups and the API is accessible to these users
You are affected if NiFi version is between 1.3.0 and 1.9.2 and the REST API is accessible to users who may not have explicit read access to all processor or controller service details within Process Groups.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to NiFi version 1.10.0 or later where this vulnerability is patched. If immediate upgrade is not feasible, restrict API access to trusted users and implement additional authorization controls at the network level.
