Description

The npm package commons-ui-styles@99.9.1 is a malicious placeholder designed for dependency confusion attacks. It declares a transitive dependency on a tarball hosted on a Google Cloud Storage bucket controlled by an unknown party, allowing arbitrary code execution during installation. Installing this package can lead to full system compromise, requiring immediate secret and key rotation and removal of the package.

Impact

Any system that installs commons-ui-styles@99.9.1 is fully compromised, as the malicious transitive dependency can execute arbitrary code during installation. All secrets and keys on the compromised system should be considered exposed and must be rotated from a separate, secure system. Removing the package alone does not guarantee removal of all malicious artifacts or backdoors.

Defensive guidance

Remove the commons-ui-styles@99.9.1 package immediately. Rotate all secrets and keys from a secure environment. Avoid installing packages with dependencies resolved from untrusted external URLs without integrity verification. Monitor package sources for dependency confusion risks. Patch status is not applicable as this is a malicious package, not a software defect with a vendor fix.

Summary

The package commons-ui-styles@99.9.1 is an empty placeholder with no legitimate content, whose sole purpose is to resolve a dependency named ltidisafe from a hardcoded URL on a Google Cloud Storage bucket. This bucket path includes 'depenconf', indicating it is used for dependency confusion attacks. When npm installs commons-ui-styles, it fetches and installs the ltidisafe package from this external source without integrity checks or version pinning, allowing the bucket owner to execute arbitrary lifecycle scripts on the installer's host. This results in full compromise of any system installing the package.
