CVE-2023-42504: PYSEC-2026-1157 - Apache Superset Allocation of Resources Without Limits or Throttling vulnerability

CVE-2023-42504 · Severity: low · CVSS 3.1 · Published 2026-07-07

Technologies: Apache Superset, apache-superset (PyPI). Vendors: Apache, PyPI.

Executive brief

Apache Superset is a data visualization and exploration platform used to create and share dashboards. An authenticated attacker can trigger a denial of service by making multiple concurrent requests to export dashboards without resource limits, potentially making the service unavailable to legitimate users.

Technical details

This vulnerability is a resource exhaustion issue (CWE-770) in Apache Superset's dashboard export functionality. An authenticated user can initiate multiple concurrent requests, each requesting multiple dashboard exports, without proper rate limiting or resource throttling. This causes unbounded resource consumption (CPU, memory, disk I/O) leading to denial of service. The attack requires authentication but no user interaction beyond sending requests. The vulnerability affects all versions before 3.0.0 and is fixed in 3.0.0 release.

Affected products
