  "summary": "CVE-2026-9743 is fixed in MongoDB on 1 platform by MongoDB 8.2.3 (version 8.2.3), released December 16, 2025. It is not reported as exploited. Patch Radar priority: High.",
  "title": "Aggregation sub-pipeline null dereference may allow DoS via crafted getMore",
  "description": "In MongoDB Server 8.0, an aggregation stage can leave its _subPipeline field null during processing of certain pipelines. If a getMore is subsequently issued on the same cursor, the server may dereference this null sub-pipeline when reattaching to the operation context, accessing an invalid address and crashing the process. This issue allows an authenticated user who can run aggregation pipelines to cause a denial of service by issuing a specially crafted aggregation followed by getMore on affected versions.",
