Summary
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.

Se supon\u00eda que una extensi\u00f3n del antiguo ajuste \"require_valid_user\", que a su vez requiere que todas y cada una de las peticiones hacia CouchDB tengan que hacerse con credenciales v\u00e1lidas, prohibiendo efectivamente cualquier petici\u00f3n an\u00f3nima. El nuevo \"require_valid_user_except_for_up\" es un ajuste desactivado por defecto que se supone que permite requerir credenciales v\u00e1lidas para todos los endpoints excepto para el endpoint \"/_up\". Sin embargo, la implementaci\u00f3n de \u00e9ste cometi\u00f3 un error que conllev\u00f3 a no aplicar las credenciales sobre ning\u00fan endpoint, cuando estaba habilitado. CouchDB versiones 3.0.1[1] y 3.1.0[2] corrige este problema."
