Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. 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. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-18209/ (Markdown: https://insights.sbomify.com/MAL-2026-18209/index.md)","id":"MAL-2026-18209","markdown":"https://insights.sbomify.com/MAL-2026-18209/index.md","name":"MAL-2026-18209","record":{"aliases":["GHSA-5x9g-7rj9-4xc8"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package is published under an internal-looking scope (@ecg-internal) and ships a stub main module that returns a Proxy of no-op functions for every property access — it provides none of the i18n functionality its name implies. Its only real behavior is firing beacon.cjs, which executes both from the declared postinstall lifecycle script (`node beacon.cjs`) and from a top-level `require('./beacon.cjs').fire()` in the main module. beacon.cjs collects the installer's hostname (via `os.hostname()`), install path (`__dirname`), current working directory, Node.js version, and package name, and POSTs them over plain HTTP to the hardcoded bare-IP endpoint http://185.158.107.175:8787/_ah/dc. The destination is not a publisher-aligned domain and the shape — internal-looking scope + hollow functional surface + install- and import-time callback with host identifiers to a bare IP — is a dependency-confusion reconnaissance probe designed to identify internal build systems that resolve the private name from the public registry.\n\nAny computer that has this package installed or running should be considered fully compromised.
