CVE-2025-49015

The Couchbase .NET SDK (client library) before 3.7.1 does not properly enable hostname verification for TLS certificates.

MEDIUM 4.9EPSS 0.21%

Does this matter?

Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.

Description

The Couchbase .NET SDK (client library) before 3.7.1 does not properly enable hostname verification for TLS certificates. In fact, the SDK was also using IP addresses instead of hostnames due to a configuration option that was incorrectly enabled by default.
