## 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.
