GridFS data disclosure and deletion via query-operator injection in file IDs in the MongoDB C++ Driver

Published Sep 10, 2026 · Updated Sep 10, 2026 · Assigned by mongodb

Description

Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB C++ 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.
