CVE-2026-88030— GridFS data disclosure and deletion via query-operator injection in file IDs in the MongoDB Ruby Driver
Quick assessment
Affected
MongoDB Ruby 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 Ruby 驱动的 GridFS 组件中，查询逻辑中对特殊字符/元素未进行充分净化，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。能够影响受影响的 application 所传递标识符的已认证用户，可能会获取超出目标范围的已存储文件内容，或者导致受影响的 bucket 中所有的 GridFS 文件块被删除，从而使已存储的文件内容无法读取。

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