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
APM server logs could contain parts of the document body from a partially failed bulk index request. Depending on the nature of the document, this could disclose sensitive information in APM Server error logs.

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

APM Server incorrectly writes document body content to error logs when bulk index requests partially fail. When some documents in a bulk request fail processing, the server may include portions of the document body in the error log message, potentially exposing sensitive data such as PII, credentials, or other confidential information that was in the failed documents.

MitigationConfigure log retention and access controls to limit exposure of APM Server error logs. Apply any available vendor patches that sanitize or redact document body content from bulk index failure messages.

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 APM Server installation and version
    Run 'apm-server version' or check the package manager for installed apm-server package. Compare the installed version against the affected version range provided by the vendor.
    Affected if APM Server is installed and the version falls within the affected range.
  2. Confirm bulk indexing is in use
    APM Server uses Elasticsearch bulk API to index traces and metrics. Verify APM Server is configured to connect to Elasticsearch and is actively processing monitoring data. Check apm-server.yml for 'output.elasticsearch' configuration.
    Affected if APM Server is configured with Elasticsearch output and is processing incoming APM data.
  3. Locate and examine APM Server error logs
    Check the configured log directory (typically /var/log/apm-server or as specified in apm-server.yml under 'logging.files.path'). Search for entries containing 'bulk' and 'error' or 'failed'.
    Affected if Error logs exist and contain bulk index failure messages.
  4. Inspect failure messages for document body content
    Review the error log entries from the previous step. Look for any plain-text content that resembles APM document data (JSON payloads with trace IDs, spans, transactions, or user-defined fields) appearing within or alongside the error messages.
    Affected if Error log entries show portions of document body content in failure messages rather than just index names or document IDs.

You are affected if APM Server is running with a vulnerable version, processing bulk index requests, and error logs contain actual document body content from failed 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.
