CVE-2026-107324— Application denial of service via integer overflow in BSON value-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 驱动程序在 BSON 值长度处理中存在整数溢出漏洞，当应用程序验证或访问格式错误的 BSON 文档时，可能导致运行时panic。无法通过身份验证的攻击者若能向受影响的应用程序提供恶意的 BSON 数据字节，可能导致受保护的应用程序进程终止，从而引发拒绝服务（DoS）攻击。该驱动程序的服务监控路径包含 panic 恢复机制，其影响范围仅限于服务器选择失败。

Vulnerability Title
Application denial of service via integer overflow in BSON value-length validation in MongoDB Go Driver
Source: CVE Program / CVE List V5
Vulnerability Description
An integer overflow in BSON value-length handling in the MongoDB Go Driver can cause a runtime panic when an application validates or accesses a malformed BSON document. An unauthenticated actor who can supply BSON bytes to an affected application may terminate an unprotected application process, causing a denial of service. The driver's server-monitoring path contains panic recovery and is limited to server-selection failure.
