CWE-297Published: June 18, 2025· Updated: Jun 17, 2026
4.9
CVSS v3.1
Official 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.
Technical Analysis
CVE-2025-49015 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), with a CVSS base score of 4.9.
