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
Kibana version 8.7.0 contains an arbitrary code execution flaw. An attacker with All privileges to the Uptime/Synthetics feature could send a request that will attempt to execute JavaScript code. This could lead to the attacker executing arbitrary commands on the host system with permissions of the Kibana process.

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

Kibana 8.7.0 contains an arbitrary code execution vulnerability in the Uptime/Synthetics feature. An attacker with All privileges to this feature can send specially crafted requests that attempt to execute JavaScript code, potentially allowing arbitrary command execution on the host with Kibana process permissions.

MitigationUpgrade Kibana to a patched version and review/revoke All privileges to the Uptime/Synthetics feature for non-admin users. Apply principle of least privilege to feature permissions.

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. Verify Kibana version
    Check the installed Kibana version by accessing the Kibana management console or running: kibana --version or checking the kibana package.json
    Affected if Version is exactly 8.7.0
  2. Confirm Uptime/Synthetics feature is accessible
    Navigate to Uptime/Synthetics in the Kibana sidebar or check feature privileges in the Kibana roles configuration
    Affected if The Uptime/Synthetics feature is present and enabled in the installation
  3. Identify users with All privileges to Uptime/Synthetics
    Review Kibana roles: go to Management > Security > Roles and inspect each role for Uptime/Synthetics feature privileges set to 'All'
    Affected if Any role grants 'All' privileges on the Uptime/Synthetics feature to non-admin users

You are affected if running Kibana 8.7.0 and any user has All privileges assigned to the Uptime/Synthetics feature.
