CVE-2026-13072 PUBLISHED

MongoDB Improper Input Validation in Compute Mode External Data Processing Leading to Memory Corruption

Assigner: mongodb
Reserved: 23.06.2026 Published: 22.07.2026 Updated: 23.07.2026

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.
