The 'adn_cli' RubyGems package at version 0.0.6 has been flagged as containing malicious code by the OpenSSF malicious packages initiative. This indicates that the package itself is intentionally harmful or contains backdoors or malware. The advisory does not provide further technical details or exploitation methods. There is no indication of a vulnerability in the package code but rather that the package is malicious by design.

Use of the 'adn_cli' version 0.0.6 package may lead to execution of malicious code on systems where it is installed. This can compromise system integrity, confidentiality, and availability depending on the payload of the malicious code. No known exploits in the wild have been reported at this time.

Avoid using the 'adn_cli' package version 0.0.6. Remove it from any systems where it is installed. Since this is a malicious package rather than a vulnerability with a patch, remediation involves not installing or uninstalling the affected version. Monitor RubyGems and trusted sources for a clean or official replacement if needed.
