MongoDB Python Driver GridFS Query Injection - CVE-2026-88029
CVE-2026-88029 Published on September 10, 2026
GridFS data disclosure and deletion via query-operator injection in file IDs in the MongoDB Python Driver
Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB Python 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 obtain stored file content beyond the intended target or cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable. The affected rename operation may also rename a stored file other than the intended target.
Vulnerability Analysis
CVE-2026-88029 can be exploited with network access, and requires small amount of user privileges. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to have no impact on confidentiality and integrity and availability.
Weakness Type
Improper Neutralization of Special Elements in Data Query Logic
The application generates a query intended to access or manipulate data in a data store such as a database, but it does not neutralize or incorrectly neutralizes special elements that can modify the intended logic of the query.
Affected Versions
MongoDB Python Driver:- Version 1.6.0 and below 4.18.1 is affected.
