CVE-2026-13072: Mongodb heap-based buffer overflow vulnerability

Mongodb · Mongodb

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.
