CVE-2026-116641: Database Tools eMudhra Certificate Trust Vulnerability

Source agreement

Evidence confidence

Short explanation

Database Tools was compiled with Golang 1.26.8, which lacks the internal denylist of known-bad CA certificates found in the crypto/x509 package. This causes trust in certificates issued by eMudhra intermediate CAs.

Why does it matter?

This vulnerability can enable attackers to manipulate TLS traffic and lead to confidentiality and integrity breaches.

What should be done?

  • Update to Golang 1.27.3
  • Follow vendor advisory recommendations
Chain of evidence and sources2 verified claims

Database Tools, eMudhra ara CA'ları tarafından verilen sertifikalara güvenilmesine neden olan Golang sürümüyle derlenmiştir.

Show the technical text from the sources

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
