If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

HTA execution grants the remote repository owner arbitrary code execution on any Windows host that invokes this function, and the fetched content can change at any time without a new package release.
