CVE-2026-107325— Application denial of service via missing BSON array length validation in 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 驱动程序中存在对 BSON 数组长度的验证不当问题。当应用程序对格式错误的四字节数组调用 或 时，可能导致越界索引和运行时恐慌（panic）。未通过身份验证的攻击者若能为受影响的应用程序提供原始 BSON 数组数据，则可能终止未受保护的应用程序进程，从而引发拒绝服务（DoS）攻击。目前尚未发现任何对机密性或完整性的影响。

Vulnerability Title
Application denial of service via missing BSON array length validation in MongoDB Go Driver
Source: CVE Program / CVE List V5
Vulnerability Description
Improper validation of a BSON array length in the MongoDB Go Driver can cause an out-of-bounds index and runtime panic when an application calls bson.RawArray.Validate or bsoncore.Array.Validate on a malformed four-byte array. An unauthenticated actor who can supply raw BSON array data to an affected application may terminate an unprotected application process, causing a denial of service. No confidentiality or integrity impact has been identified.
