Summary
DB Tools rely on the TLS implementation in Golang's standard library, which uses the system CA store and an internal denylist of known-bad CA certificates in the crypto/x509 package. Golang 1.27.3 adds eMudhra certificates to this list, but DB Tools version 100.19.0 was compiled with Golang 1.26.8, which lacks this check. The issue is resolved in DB Tools 100.20.0 by updating to Golang 1.27.3.
Risk Assessment
Organizations using DB Tools 100.19.0 may accept TLS connections with eMudhra certificates that should be blocked, potentially facilitating man-in-the-middle attacks. The risk affects the integrity and confidentiality of database connections.
Recommendation
Update DB Tools to version 100.20.0 or later, which includes Golang 1.27.3 with the expanded CA denylist. Verify the Golang version used to compile the tools.

Etrel INCH AC charging station management web interface prior to firmware versions 7.1.2 and 8.0.1 contains a hard-coded default credentials vulnerability that allows remote attackers to gain full Administrator access by authenticating with the factory-default account. Attackers can log in over cleartext HTTP to obtain complete charger configuration, OCPP ChargePoint Identity, and CSMS WebSocket connection details, enabling unauthorized administrative control of the charging station.
- CVE-2026-95860Critical
In node-opcua (an OPC UA implementation for TypeScript and Node.js), versions 2.42.0 through 2.180.0 do not honor namespace-level access control configured via setDefaultRolePermissions for nodes without explicit per-node permissions. SessionContext.getApplicableRolePermissions reads a missing or null value instead of the configured namespace field, and the null result is treated permissively. As a result, an anonymous network client can write variables or call bound methods when an operator relied on restrictive namespace defaults.

Original NVD description (English source)
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
