It only works under certain conditions, which makes it harder to pull off. CVSS: high attack complexity.
Someone has to open, click or run something first. CVSS: user interaction required.
A successful attack can read data and change data. CVSS impact.
A successful attack gives full control of the affected system. CISA: technical impact total.

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
