CVE-2026-88033— GridFS data disclosure and deletion via query-operator injection in file IDs in the MongoDB Java Driver

Quick assessment

Affected

MongoDB Java 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 Java Driver是美国MongoDB公司开源的一个数据库连接驱动。 MongoDB Java Driver 3.3.0版本至5.11.1之前版本存在输入验证错误漏洞，该漏洞源于GridFS组件数据查询逻辑中特殊元素中和不当，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标识符，可能使经过身份验证且能影响标识符的攻击者获取超出预期目标的存储文件内容，或导致受影响存储桶中所有GridFS文件块被删除并使存储文件内容不可读，受影响的rename操作还可能重命名非预期目标文件。

Vulnerability Title

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