The npm package chain-api-sdk was found to contain malware. According to the GitHub Advisory (GHSA-6vrp-3g92-phhf), any computer with this package installed or running should be considered fully compromised.\n\nImmediate action is required: all secrets and keys stored on affected computers must 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 compromise.\n\nThe advisory was published on July 9, 2026, and indicates the severity is critical due to the potential for complete system compromise and unauthorized access to sensitive credentials and keys.
