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 discovered in Couchbase Server before 7.0.4. Sample bucket loading may leak internal user passwords during a failure.

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 · moderate confidence

In Couchbase Server versions before 7.0.4, the sample bucket loading feature contains a vulnerability where internal user passwords may be leaked to logs or error output during failure conditions. This allows unauthorized access to internal user credentials.

MitigationUpgrade Couchbase Server to version 7.0.4 or later to remediate this vulnerability. Review logs for any evidence of password leakage since the time of introduction.

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. Determine installed Couchbase Server version
    Access the Couchbase Web Console and navigate to the 'Server Nodes' page, or run the 'couchbase-cli server-info' command-line tool, to identify the exact version number of the installation
    Affected if The installed version falls within 6.6.0-6.6.3, 7.0.0, 7.0.1, 7.0.2, or 7.0.3
  2. Verify if sample bucket loading has been attempted
    Check the Couchbase Web Console under 'Sample Buckets' in the bucket configuration area, or review the server startup logs for any references to sample bucket loading operations
    Affected if Sample buckets were loaded or attempted to be loaded on the affected version
  3. Inspect logs for credential leakage
    Search all Couchbase server log files (typically found in /opt/couchbase/var/lib/couchbase/logs/ or via the UI Logs section) for patterns matching passwords, credentials, or authentication tokens in error messages or failure conditions related to bucket operations
    Affected if Plaintext passwords or credentials appear in any log entries or error output
  4. Review error output during bucket operations
    Monitor any console output, diagnostic files, or API responses generated when loading or accessing sample buckets, particularly during failure or error scenarios
    Affected if Error messages contain sensitive authentication data

You are affected if running any Couchbase Server version from 6.6.0 to 6.6.3, 7.0.0, 7.0.1, 7.0.2, or 7.0.3 AND sample bucket loading was used, with password leakage present in logs or error output.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

Upgrade available Upgrade to a release after 6.6.3
Interim mitigation

Upgrade Couchbase Server to version 7.0.4 or later to remediate this vulnerability. Review logs for any evidence of password leakage since the time of introduction.

Recommended fix High confidence

7.0.4 or later (7.0.3 is also fixed per the 'before 7.0.4' statement in the description)

  1. Verify current Couchbase Server version by checking the UI or running: couchbase-server --version
  2. Plan and schedule a maintenance window for the upgrade
  3. Back up all cluster data and configuration - use cbbackup or enterprise backup features
  4. For cluster upgrades, follow Couchbase rolling upgrade procedure: upgrade one node at a time, rebalance after each
  5. Download Couchbase Server 7.0.4 or later from docs.couchbase.com
  6. Install the new version on each node, starting with secondary nodes before the primary
  7. After installing on all nodes, complete a rebalance to ensure cluster stability
  8. Verify the sample bucket loading no longer exposes passwords in failure logs
