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
Elastic Cloud Enterprise (ECE) versions prior to 1.1.4 contain an information exposure vulnerability. It was discovered that certain exception conditions would result in encryption keys, passwords, and other security sensitive headers being leaked to the allocator logs. An attacker with access to the logging cluster may obtain leaked credentials and perform authenticated actions using these credentials.

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 Cloud Enterprise versions before 1.1.4 contain an information exposure vulnerability where exception conditions leak encryption keys, passwords, and security-sensitive headers to allocator logs. An attacker with access to the logging infrastructure can obtain these exposed credentials and perform authenticated actions.

MitigationUpgrade ECE to version 1.1.4 or later to patch the vulnerability. Additionally, audit log access controls and review existing logs for any leaked credentials that may have been captured.

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 Elastic Cloud Enterprise version
    Run command: docker images | grep -i elastic-cloud-enterprise or check /opt/elastic/cloud/ece-installation/.installed version file if available. Alternatively, query the ECE API endpoint: GET /api/v1/platform/cluster/stats
    Affected if Installed version is any version before 1.1.4 (e.g., 1.1.0, 1.1.1, 1.1.2, 1.1.3)
  2. Verify allocator logging is enabled
    Check ECE configuration files in /opt/elastic/cloud/ece-installation/ for allocator logging settings. Look for logging-related configuration in ece-config.yml or allocator configuration
    Affected if Allocator logging is enabled and logs are written to disk or a logging infrastructure that could be accessed by an attacker
  3. Examine allocator log files for sensitive data exposure
    Locate allocator logs typically stored in /var/log/elastic/allocator/ or within the Docker container logs directory. Search for patterns like 'password', 'key', 'Authorization', 'X-Elastic-Api-Key' in exception/error logs
    Affected if Logs contain plaintext passwords, encryption keys, or security-sensitive headers in exception stack traces or error messages
  4. Review log access controls
    Audit file system permissions on log directories and review who has access to the logging infrastructure (e.g., log aggregation systems like Elasticsearch, Splunk, or syslog)
    Affected if Log files or log aggregation systems are accessible to unauthorized users or processes beyond the intended administration team

Environment is affected if Elastic Cloud Enterprise version is below 1.1.4 AND allocator logs are being generated, as exception conditions in those logs may contain exposed credentials.

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