undefensive

Lacking protective walls

Not defensive; open to criticism or challenge without feeling threatened.

Someone undefensive accepts feedback without bristling or making excuses: She was remarkably undefensive about her mistakes.

The word suggests emotional security—a willingness to acknowledge flaws rather than protect against perceived attacks.
