Authenticated Resource Exhaustion in MongoDB via Queryable Encryption

Publication date: 2026-07-22

Last updated on: 2026-07-22

Assigner: MongoDB, Inc.

Description
An authenticated user can cause excessive CPU consumption or out-of-memory conditions on a MongoDB server by sending a crafted Queryable Encryption find payload containing an unvalidated field used to control an internal computation loop. The resulting resource exhaustion degrades availability for other operations.

Executive Summary

This vulnerability allows an authenticated user to send a specially crafted payload to a MongoDB server using Queryable Encryption. The payload contains a field that controls an internal computation loop without validation, causing excessive CPU usage or memory consumption. This leads to resource exhaustion and degrades server availability for other operations.

Impact Analysis

If exploited, this vulnerability can cause your MongoDB server to become slow or unresponsive due to high CPU or memory usage. This may disrupt database operations, affect performance for all users, and potentially lead to service outages or downtime.

Mitigation Strategies

Apply the latest MongoDB security patches immediately to address the crafted Queryable Encryption payload issue. Monitor CPU and memory usage for unusual spikes. Restrict authenticated user access to only necessary operations and limit query complexity.
