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-2026-5028/ (Markdown: https://insights.sbomify.com/MAL-2026-5028/index.md)","id":"MAL-2026-5028","markdown":"https://insights.sbomify.com/MAL-2026-5028/index.md","name":"MAL-2026-5028","record":{"aliases":["GHSA-jfh5-5qvf-47fj"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"sorenson-webfonts@99.9.1 is a hollow package: index.js is a 2-line stub (`'use strict'; module.exports = {};`), author/description fields are empty, and the version number 99.9.1 is the high-version pattern characteristic of dependency-confusion attempts to override an internal package. The package's only effect on install is to pull a single dependency, `ltidisafe`, directly from an HTTPS tarball URL on a Google Cloud Storage bucket (`https://ltidi.storage.googleapis.com/depenconf/ltidisafe-2.8.2.tgz`) — a non-registry, non-publisher location whose path segment `depenconf` suggests dependency-confusion staging. Resolving this dependency causes npm to fetch and execute the lifecycle scripts of an off-registry tarball whose contents are not pinned by integrity hash and not subject to registry review. The package name (`sorenson-webfonts`) bears no relation to the dependency name or to any stated purpose; there is no advertised webfont functionality in the shipped code. The combination of empty body, placeholder metadata, 99.9.x version, and an unrelated off-registry tarball pulled from a bucket path named after dependency confusion is the smuggling-vehicle shape rather than a legitimate library.\n\nAny computer that has this package installed or running should be considered fully compromised.
