Received Received - Intake

Atlas Search Access Bypass in MongoDB Server

Publication date: 2026-07-22

Last updated on: 2026-07-22

Assigner: MongoDB, Inc.

Description

An issue in the server’s Atlas Search integration allows an authenticated user to bypass per-user access controls. In sharded topologies, the $search and $searchMeta aggregation stages use internal routing that is normally populated only by the trusted router during sharded search planning. Due to insufficient input validation, an authenticated client can supply these fields directly.

Attack-Flow Graph

Executive Summary

This vulnerability exists in MongoDB Atlas Search integration where an authenticated user can bypass per-user access controls. In sharded database setups, the $search and $searchMeta aggregation stages use internal routing that should only be populated by the trusted router during search planning. However, due to insufficient input validation, an authenticated client can directly supply these fields, potentially accessing data they shouldn't.

Impact Analysis

If exploited, this vulnerability could allow an authenticated attacker to access sensitive data they are not authorized to view by bypassing access controls. This could lead to unauthorized data exposure, data leaks, or privacy violations depending on the data stored in the database.

Compliance Impact

This vulnerability could lead to non-compliance with data protection regulations like GDPR or HIPAA by enabling unauthorized access to personal or sensitive health data. Organizations using MongoDB Atlas Search in sharded topologies may face compliance violations, legal penalties, or reputational damage if this flaw is exploited.

Mitigation Strategies

Apply the latest MongoDB Atlas Search patch or update to a version that fixes the insufficient input validation issue. Restrict authenticated user permissions to prevent unauthorized access to $search and $searchMeta aggregation stages.
