The npm package cdocs-markdoc was found to contain malware. According to the GitHub Advisory (GHSA-8g7g-fgv9-26pp), any computer with this package installed or running should be considered fully compromised.\n\nThe advisory recommends that all secrets and keys stored on affected computers be rotated immediately from a different, uncompromised system. While the package should be removed, there is no guarantee that removal will eliminate all malicious software that may have been installed as a result of the initial compromise, given that the attacker may have gained full control of the system.\n\nUsers should treat any system that has run this package as potentially containing persistent malware and take appropriate incident response measures."
