CVE-2025-49015
low-risk
Published 2025-06-18
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.
