CVE-2020-1955

Date: May 20, 2020

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 3.0.1[1] and 3.1.0[2] fix this issue.
