CVE-2026-116641— The DB Tools trust certificates issued by recoverable eMudhra intermediate CAs

Quick assessment

Affected

MongoDB Database Tools

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.

DB Tools 依赖 Golang 标准库中的 TLS 实现，该实现通常使用系统的证书颁发机构（CA）存储。然而，包还维护了一份内部黑名单，用于拦截已知恶意的 CA 证书。Golang 1.27.3 已将 eMudhra 证书加入该黑名单。 DB Tools 100.19.0 是使用 Golang 1.26.8 编译的，该版本尚未包含此项检查。此问题已在 DB Tools 100.20.0 中通过升级至 Golang 1.27.3 得到修复。

Vulnerability Title

The DB Tools trust certificates issued by recoverable eMudhra intermediate CAs

Source: CVE Program / CVE List V5

Vulnerability Description

The DB Tools rely on the TLS implementation in Golang’s standard library, which generally uses the system CA store. However, the crypto/x509 package also has its own internal denylist of known-bad CA certificates. Golang 1.27.3 adds the eMudhra certificates to this list. DB Tools version 100.19.0 was compiled with Golang 1.26.8, which does not include this check. The issue is resolved by updating to Golang 1.27.3 in DB Tools 100.20.0
