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 · unedited
The ExtractCCDAAttributes Processor in Apache NiFi 1.2.0 through 1.19.1 does not restrict XML External Entity references. Flow configurations that include the ExtractCCDAAttributes Processor are vulnerable to malicious XML documents that contain Document Type Declarations with XML External Entity references. The resolution disables Document Type Declarations and disallows XML External Entity resolution in the ExtractCCDAAttributes Processor.

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 confidence

The ExtractCCDAAttributes Processor in Apache NiFi 1.2.0 through 1.19.1 does not restrict XML External Entity (XXE) references, allowing malicious XML documents with crafted Document Type Declarations (DTDs) to reference external entities and potentially exfiltrate sensitive data or perform server-side request forgery.

MitigationUpgrade Apache NiFi to version 1.20.0 or later, which disables Document Type Declarations and disallows XML External Entity resolution in the ExtractCCDAAttributes Processor. Alternatively, avoid processing untrusted XML with the ExtractCCDAAttributes Processor until upgrade is possible.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check the installed Apache NiFi version
    Locate the NiFi installation directory and check the release file or run 'nifi.sh version' if available. Common locations include /opt/nifi or the installation root directory.
    Affected if The installed version is >= 1.2.0 and <= 1.19.1
  2. Identify if the ExtractCCDAAttributes Processor exists in any flow
    Review NiFi canvas for processors named 'ExtractCCDAAttributes' or search in the NiFi repository XML files (flow.json or the flow XML export) for this processor type.
    Affected if The processor is present in any active or saved data flow configuration
  3. Determine if the processor is actively running
    In the NiFi web UI, locate the ExtractCCDAAttributes Processor and check its status. Alternatively, inspect the flow configuration to see if the processor is enabled.
    Affected if The processor is in a 'Running' state and scheduled to execute
  4. Assess the source of XML data being processed
    Inspect the incoming connections to the ExtractCCDAAttributes Processor to determine if the XML data originates from untrusted or external sources.
    Affected if The processor processes XML from untrusted or external sources

You are affected if NiFi version is between 1.2.0 and 1.19.1 AND the ExtractCCDAAttributes Processor is actively running and processing untrusted XML documents.

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.

Upgrade available Upgrade to a release after 1.19.1
Interim mitigation

Upgrade Apache NiFi to version 1.20.0 or later, which disables Document Type Declarations and disallows XML External Entity resolution in the ExtractCCDAAttributes Processor. Alternatively, avoid processing untrusted XML with the ExtractCCDAAttributes Processor until upgrade is possible.

Recommended fix High confidence

Nifi 1.20.0 or later

  1. Upgrade Apache NiFi to version 1.20.0 or later to include the security fix that disables Document Type Declarations and XML External Entity resolution in the ExtractCCDAAttributes Processor
Caveat Minimal - the fix may affect workflows that intentionally used XXE or DTD processing in ExtractCCDAAttributes
