CVE-2020-15095
MediumCVSS 4.4Summary
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 "<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>". The password value is not redacted and is printed to stdout and also to any generated log files.
Risk Assessment
Passwords may leak into logs and console output, allowing unauthorized parties to obtain credentials for repositories or registries.
Recommendation
Update npm CLI to version 6.14.6 or later and review and purge existing log files for exposed credentials.
