The npm package temp-cloak was found to contain malware. According to the GitHub Advisory (GHSA-rr2q-r4vq-r6cm), any computer with this package installed or running should be considered fully compromised.\n\nThe advisory recommends immediate action: all secrets and keys stored on affected computers should be rotated 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 compromise.\n\nThe severity is critical due to the potential for complete system compromise and the risk of credential theft or lateral movement to other systems.
