If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

Package @an1mshnpmb9c84920/oidc-cross-cafb9d929e@1.0.0 contains three files and no observed behaviors that read installer secrets, fetch or execute remote code, open a backdoor, or relay caller data to a third party. The randomized scope and name are consistent with a dependency-confusion probe or placeholder publication, but the shipped code itself does not perform any action against the installer.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
