CVE-2024-25673Network attack vector

User redirection via blindly copied Host header

Published Sep 19, 2024 · Updated Mar 19, 2025

HTTP Host header injection in Couchbase Server before 7.2.6 and 7.6.0 through 7.6.1 allows remote attackers to control redirects. The HTTP response path blindly copies the request's untrusted Host value into the Location header instead of validating the redirect authority. Exploitation requires user interaction with the resulting redirect and exposes the user to an attacker-chosen destination.
