The npm package flight-compare-analyzer was found to contain malware. According to the GitHub Advisory (GHSA-wwp4-2j5x-f2m9), 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.
