Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The Couchbase .NET SDK (CouchbaseNetClient) before 3.7.1 does not properly enable hostname verification for TLS certificates, and it connected using IP addresses because a configuration option was incorrectly enabled by default. The source does not describe the specific attacker position or the impact in detail. Upgrade CouchbaseNetClient to version 3.7.1 or later.
