+===========================================================
+CVE-2020-1955: Apache CouchDB Remote Privilege Escalation
+===========================================================
+
+:Date: 19.05.2020
+
+:Affected: 3.0.0
+
+:Severity: Medium
+
+:Vendor: The Apache Software Foundation
+
+Description
+===========
+
+CouchDB version 3.0.0 shipped with a new configuration setting that
+governs access control to the entire database server called
+`require_valid_user_except_for_up`. It was meant as an extension to the
+long-standing setting `require_valid_user`, which in turn requires that
+any and all requests to CouchDB will have to be made with valid
+credentials, effectively forbidding any anonymous requests.
+
+The new `require_valid_user_except_for_up` is an off-by-default setting
+that was meant to allow requiring valid credentials for all endpoints
+except for the `/_up` endpoint.
+
+However, the implementation of this made an error that lead to not
+enforcing credentials on any endpoint, when enabled.
+
+CouchDB versions :ref:`3.0.1 <release/3.0.1>` and 3.1.0
+fix this issue.
+
+Mitigation
+==========
+
+Users who have not enabled `require_valid_user_except_for_up` are not
+affected.
+
+Users who have it enabled can either disable it again, or upgrade to
+CouchDB versions :ref:`3.0.1 <release/3.0.1>` and 3.1.0.
