Improper Input Handling in MongoDB Go Driver GridFS

Publication date: 2026-09-10

Last updated on: 2026-09-10

Assigner: MongoDB, Inc.

Description
Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB Go Driver can cause a caller-supplied structured file identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence the identifier passed by an affected application may cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable.

Executive Summary

This vulnerability involves improper handling of special elements in data query logic within MongoDB's GridFS component. An authenticated user can manipulate a structured file identifier so that it is treated as a query condition instead of a literal identifier. This could lead to the deletion of all GridFS file chunks in a bucket, making stored file content unreadable.

Impact Analysis

If exploited, this vulnerability could result in the permanent loss of data stored in GridFS buckets. Users relying on MongoDB for file storage may experience unavailability or corruption of critical files, leading to operational disruptions or data breaches.

Compliance Impact

This vulnerability could lead to non-compliance with data protection regulations such as GDPR or HIPAA by causing unauthorized data deletion or loss of integrity. Organizations may face legal penalties, reputational damage, or failure to meet regulatory requirements for data availability and security.

Mitigation Strategies

Update the MongoDB Go Driver to the latest version that patches this vulnerability. Ensure proper input validation for GridFS file identifiers to prevent malicious queries. Restrict user permissions to minimize the impact of unauthorized file chunk removal.
