CVE-2023-49932Network attack vector

Restricted-host access via incomplete cURL allowlist

Published Feb 28, 2024 · Updated Nov 7, 2024

Authorization bypass in Couchbase Server 5.x through 7.2.3 allows remote attackers to access restricted hosts through SQL++ cURL. The Query Service's SQL++ N1QL cURL allowlist fails to prevent requests to hosts designated as restricted; Couchbase has not disclosed the faulty comparison or parsing path. A network-delivered query and user interaction are required, and the documented consequence is limited to reaching otherwise blocked hosts.
