The svelte-cache-kit npm package version 1.0.0 contains malicious code that can fully compromise any computer on which it is installed or running. The package does not exhibit suspicious behavior during install or import, but its presence indicates a severe security risk. Systems with this package should be considered fully compromised, and all stored secrets and keys must be rotated from a separate, secure machine. Removing the package alone does not guarantee removal of all malicious software introduced by it.
