CVE-2026-88036— GridFS data disclosure and deletion via query-operator injection in file IDs in the MongoDB C Driver
Quick assessment
Affected
MongoDB C 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.
这段漏洞描述主要涉及 MongoDB C 驱动中 GridFS 组件的安全问题。以下是专业、准确的中文翻译： 翻译如下： 在 MongoDB C 驱动的 GridFS 组件中，数据查询逻辑中对特殊元素的中和处理不当，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，而非字面量标识符。能够影响受影响的 Application 所传递的标识符的认证用户，可能获取超出预期目标的存储文件内容，或者导致受影响桶（bucket）中的所有 GridFS 文件分片（chunks）被删除，从而使存储的文件内容变得不可读。 ---

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