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 authenticated malicious user could initiate multiple concurrent requests, each requesting multiple dashboard exports, leading to a possible denial of service. This issue affects Apache Superset: before 3.0.0

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

An authenticated attacker can send multiple concurrent requests for dashboard exports without proper rate limiting or resource throttling, causing excessive server resource consumption that leads to denial of service for other users.

MitigationUpgrade to Apache Superset 3.0.0 or later. Additionally, implement rate limiting on dashboard export endpoints and consider per-user resource quotas to mitigate similar issues.

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 Apache Superset version
    Run command: pip show apache-superset or check the version in your package manager. Also check the Superset UI: navigate to Settings > About or check the version displayed in the bottom-left of the main interface.
    Affected if The installed version is below 3.0.0 (e.g., 2.x.x, 1.5.x, etc.)
  2. Verify dashboard export functionality exists
    Log in as an authenticated user, open any dashboard, and locate the export option (typically in the dashboard menu or actions dropdown). Confirm the export feature is present and functional.
    Affected if The dashboard export feature is enabled and accessible to regular authenticated users (not just admins)
  3. Check for rate limiting on export endpoints
    Review your web server configuration (Nginx/Apache) or Superset configuration (superset_config.py) for rate limiting rules. Look for rate_limit settings or middleware that throttles requests to /api/v1/dashboard/export/ or similar export endpoints.
    Affected if No rate limiting is configured on dashboard export endpoints, or rate limits are set excessively high (e.g., no requests per minute restrictions)
  4. Inspect concurrent request handling
    Check Superset configuration for worker limits and timeout settings. Review gunicorn/supervisor configuration for max_connections, worker_timeout, and request timeout values related to export operations.
    Affected if Workers are configured without request timeouts or resource limits on export operations

You are affected if Apache Superset is installed at a version below 3.0.0 and the dashboard export feature is accessible to authenticated users without rate limiting configured on export endpoints.

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.

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.

Upgrade available Upgrade to 3.0.0 or later
Fixed in 3.0.0
Interim mitigation

Upgrade to Apache Superset 3.0.0 or later. Additionally, implement rate limiting on dashboard export endpoints and consider per-user resource quotas to mitigate similar issues.

Recommended fix High confidence

3.0.0

  1. 1. Review Apache Superset 3.0.0 release notes for any breaking changes or migration requirements
  2. 2. Create a full backup of the Superset metadata database
  3. 3. Test the upgrade in a non-production environment first
  4. 4. Stop the Superset services (celery workers, web server, etc.)
  5. 5. Upgrade Superset package to version 3.0.0 using your package manager (e.g., pip install apache-superset==3.0.0 or helm upgrade for Kubernetes deployments)
  6. 6. Run database migrations: superset db upgrade
  7. 7. Clear cached data: superset cache clear
  8. 8. Restart all Superset services
Caveat Major version upgrade from 2.x to 3.0.0 may include breaking changes; review release notes for database schema changes, deprecated features, and configuration updates before upgrading
