AI-suggested

Update MongoDB Database Tools to version 100.20.0 or later, which is compiled with Golang 1.27.3 and includes the updated denylist of known-bad CA certificates. This official fix resolves the improper certificate validation issue. No other mitigation is required if the update is applied.

Description

CVE-2026-116641 is a vulnerability in MongoDB Database Tools prior to version 100.20.0 caused by improper certificate validation. The tools rely on Golang's TLS implementation, which includes an internal denylist of known-bad CA certificates. Versions compiled with Golang 1.26.8 lack the updated denylist that includes eMudhra certificates, leading to potential trust of revoked or malicious certificates. This issue is fixed in Database Tools version 100.20.0, which uses Golang 1.27.3 with the updated denylist.
