According to the GitHub Security Advisory (GHSA-q9x5-95j3-g76v), any computer that has 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.
