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
An issue was identified that allowed the unsafe deserialization of java objects from hadoop or spark configuration properties that could have been modified by authenticated users. Elastic would like to thank Yakov Shafranovich, with Amazon Web Services for reporting this issue.

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

Elastic products allowed unsafe deserialization of Java objects from Hadoop or Spark configuration properties that could be modified by authenticated users, potentially enabling remote code execution.

MitigationUpdate Elastic products to the patched version as specified in the security advisory. If immediate patching is not possible, restrict or audit write access to Hadoop/Spark configuration properties for authenticated users.

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. Identify installed Elasticsearch version
    Run `curl -XGET 'localhost:9200/'` or check the elasticsearch logs/startup banner for the version number
    Affected if Version is < 7.17.11 or >= 8.0.0 and < 8.9.0
  2. Check if Hadoop integration is configured
    Look for Hadoop-related configuration in elasticsearch.yml files or inspect cluster settings via `GET /_cluster/settings?include_defaults=true` for properties containing 'hadoop' or 'org.apache.hadoop'
    Affected if Hadoop configuration properties exist in the Elasticsearch configuration
  3. Check if Spark integration is configured
    Inspect cluster settings via `GET /_cluster/settings?include_defaults=true` for properties containing 'spark' or 'org.apache.spark'
    Affected if Spark configuration properties exist in the Elasticsearch configuration
  4. Verify user access to configuration APIs
    Review Elasticsearch role definitions and security settings to determine which authenticated users can access the APIs that modify Hadoop or Spark configuration properties (typically via PUT/POST to _cluster/settings or ingest pipeline settings)
    Affected if Authenticated users have write access to modify Hadoop or Spark configuration properties without restricted review

You are affected if your Elasticsearch version falls within the vulnerable ranges AND Hadoop or Spark integration is enabled with users able to modify their configuration properties.

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.

Upgrade available Upgrade to 7.17.11 / 8.9.0 or later
Fixed in 7.17.118.9.0
Interim mitigation

Update Elastic products to the patched version as specified in the security advisory. If immediate patching is not possible, restrict or audit write access to Hadoop/Spark configuration properties for authenticated users.

Recommended fix High confidence

7.17.11 (7.x branch) or 8.9.0 (8.x branch)

  1. Backup your Elasticsearch cluster data and configuration before upgrading.
  2. Review the Elasticsearch upgrade documentation at https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-upgrade.html
  3. For Elasticsearch 7.x: Upgrade to version 7.17.11 or later
  4. For Elasticsearch 8.x: Upgrade to version 8.9.0 or later
  5. After upgrading, verify that the cluster is healthy and all nodes have joined successfully using the _cluster/health API
Caveat Review the breaking changes for your version upgrade in the Elasticsearch migration guide; upgrading across major versions (e.g., 7.x to 8.x) has significant breaking changes
