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. In couchbase-cli, server-eshell leaks the Cluster Manager cookie.

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

An information disclosure vulnerability in Couchbase Server's couchbase-cli tool allows server-eshell to leak the Cluster Manager authentication cookie. An attacker who obtains this cookie could potentially impersonate an administrator and gain unauthorized access to cluster management functions.

MitigationUpgrade Couchbase Server to version 7.0.4 or later to obtain the patch. If immediate upgrading is not feasible, avoid using the server-eshell component and ensure no unauthorized parties can observe CLI command outputs containing sensitive session data.

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 Couchbase Server installation and version
    Run 'couchbase-cli --version' or check the installed package version using your system's package manager (dpkg, rpm, brew, etc.)
    Affected if The installed version is below 7.0.4 (e.g., 7.0.3, 7.0.2, 6.6.x, etc.)
  2. Check for couchbase-cli usage with server-eshell
    Review any scripts, automation, or documentation that invoke 'couchbase-cli server-eshell' command
    Affected if The server-eshell component of couchbase-cli is being used to interact with the Cluster Manager
  3. Inspect CLI command outputs for credential leakage
    Examine terminal outputs, log files, or shell history where couchbase-cli commands have been executed, looking for authentication cookie or session token strings
    Affected if Authentication cookies or session tokens appear in plain text in any output or log files associated with couchbase-cli operations
  4. Verify cluster manager accessibility
    Check network exposure of Couchbase Cluster Manager ports (8091, 18091, etc.) and review access logs for unauthorized session reuse
    Affected if The Cluster Manager is network-accessible and there are signs of session cookie reuse from potentially leaked credentials

You are affected if Couchbase Server version is below 7.0.4 AND the couchbase-cli server-eshell component is in use, as this combination enables the authentication cookie disclosure.

Upgrade available Upgrade to 7.0.4 or later
Fixed in 7.0.4
Interim mitigation

Upgrade Couchbase Server to version 7.0.4 or later to obtain the patch. If immediate upgrading is not feasible, avoid using the server-eshell component and ensure no unauthorized parties can observe CLI command outputs containing sensitive session data.

Recommended fix High confidence

7.0.4

  1. 1. Back up all Couchbase Server data and cluster configuration before starting the upgrade.
  2. 2. Review the official Couchbase Server 7.0.4 release notes for any migration requirements or known issues.
  3. 3. Plan a maintenance window as the upgrade will require cluster downtime.
  4. 4. Perform a rolling upgrade or offline upgrade following Couchbase documentation, upgrading to version 7.0.4 or later.
  5. 5. After upgrade, verify the cluster is functioning correctly and the couchbase-cli commands work as expected.
  6. 6. Verify that server-eshell no longer leaks the Cluster Manager cookie by testing couchbase-cli operations.
Caveat Review release notes for any configuration or compatibility changes when upgrading to 7.0.x
