The vulnerability (GHSA-fqw7-8v6m-2f86) was identified in the npm package 'hulp', discovered and published to the GitHub Advisory Database on September 2, 2020, with the latest update on January 9, 2023. This critical security issue affects all versions of the package, with no patched versions available (GitHub Advisory).

The vulnerability has been assigned a Critical severity rating with a CVSS score of 9.8. The CVSS base metrics indicate Network attack vector, Low attack complexity, No privileges required, No user interaction needed, Unchanged scope, and High impact on Confidentiality, Integrity, and Availability. The vulnerability is classified under CWE-506 (GitHub Advisory).

The malicious package contains harmful code in its preinstall script that establishes communication with a Command and Control server, enabling the execution of arbitrary commands. Any system with this package installed should be considered fully compromised, potentially giving complete control to malicious actors (GitHub Advisory).

The package is inherently malicious and becomes active upon installation. The exploitation requires no user interaction beyond the initial package installation, making it highly exploitable with low complexity (GitHub Advisory).

Security experts recommend immediate removal of the package, though this may not be sufficient to eliminate all malicious software resulting from its installation. All secrets and keys stored on affected systems should be rotated immediately from a different, uncompromised computer (GitHub Advisory).
