CVE-2026-88029— GridFS data disclosure and deletion via query-operator injection in file IDs in the MongoDB Python Driver
Quick assessment
Affected
MongoDB Python Driver
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
MongoDB Python 驱动中 GridFS 组件在数据查询逻辑中对特殊元素未进行正确中和（neutralization），可能导致调用方提供的结构化文件标识符被解释为查询条件，而非作为字面量标识符处理。若经过认证的用户能够影响受影响应用程序所传递的标识符，则可能获取超出预期目标范围的已存储文件内容，或导致受影响桶（bucket）中所有 GridFS 文件块被删除，从而使得已存储的文件内容不可读。受影响的 （重命名）操作还可能将非目标文件也一并重命名。

Vulnerability Title
GridFS data disclosure and deletion via query-operator injection in file IDs in the MongoDB Python Driver
Source: CVE Program / CVE List V5
Vulnerability Description
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.
