CVE-2026-13072

CRITICAL 9.2 ALL-YEARS

Published 2026-07-22 · Last modified 2026-07-24 · mongodb · NVD: Analyzed

When compute mode is enabled on a standalone mongod instance, insufficient validation of externally sourced BSON data during aggregation pipeline processing can result in memory corruption, potentially leading to process termination or other unintended behavior. This configuration is non-default and requires explicit enablement at startup.
