Received Received - Intake

Memory Corruption in MongoDB Aggregation Pipeline

Publication date: 2026-07-22

Last updated on: 2026-07-22

Assigner: MongoDB, Inc.

Description
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.

Executive Summary

This vulnerability occurs in MongoDB when compute mode is enabled on a standalone mongod instance. It involves insufficient validation of BSON data from external sources during aggregation pipeline processing, which can lead to memory corruption. This may cause the process to terminate or behave unpredictably. The compute mode setting is not enabled by default and must be explicitly configured at startup.

Impact Analysis

The impact includes potential process crashes or unintended behavior due to memory corruption. An attacker could exploit this to disrupt database operations or gain unauthorized access if they can submit maliciously crafted BSON data. Since the compute mode is non-default, only systems with this specific configuration are at risk.

Mitigation Strategies

Disable compute mode on standalone mongod instances if enabled. Ensure no external BSON data is processed in aggregation pipelines. Restart mongod with default settings if compute mode was active.
