Authenticated Resource Exhaustion in MongoDB via Queryable Encryption

Publication date: 2026-07-22

Last updated on: 2026-08-05

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.

Attack-Flow Graph

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.

Detection Guidance

This vulnerability involves excessive CPU or memory usage due to a crafted Queryable Encryption find payload. Monitor for unusual resource consumption spikes on MongoDB servers. Check MongoDB logs for repeated find operations with large or malformed payloads. Use system monitoring tools like top, htop, or ps to detect abnormal CPU or memory usage by mongod processes.

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.

Compliance Impact

This vulnerability can lead to resource exhaustion, causing denial of service which may violate availability requirements in GDPR (Article 32) and HIPAA (Security Rule). Excessive CPU or memory consumption could disrupt system operations, potentially leading to unauthorized data access or processing delays.

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.
