Versions of the npm CLI prior to 6.14.6 are vulnerable to an information exposure vulnerability through log files. The CLI supports URLs like ://[[:]@][:][:][/]. The password value is not redacted and is printed to stdout and also to any generated log files.
Information written to log files can be of a sensitive nature and give valuable guidance to an attacker or expose sensitive user information.

Different log files may be produced and stored for:
