CVE-2026-88031— GridFS data deletion via query-operator injection in file IDs in the MongoDB Go Driver

Quick assessment

Affected
MongoDB Go 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 Go 驱动中 GridFS 组件的数据查询逻辑中存在特殊元素未正确中和（即未正确过滤或转义）的缺陷，可能导致由调用方提供的结构化文件标识符被解析为查询条件，而非作为字面量标识符处理。能够影响受漏洞应用程序所传递的标识符的经过身份验证的用户，可能致使受影响存储桶中的所有 GridFS 文件块被删除，从而导致已存储的文件内容无法读取。

Vulnerability Title
GridFS data deletion via query-operator injection in file IDs in the MongoDB Go 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 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.
