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-2026-15536/ (Markdown: https://insights.sbomify.com/MAL-2026-15536/index.md)","id":"MAL-2026-15536","markdown":"https://insights.sbomify.com/MAL-2026-15536/index.md","name":"MAL-2026-15536","record":{"aliases":["GHSA-4hpj-q7v8-mjf7"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"package.json declares a dependency whose key equals the package's own name (`ir-annuities-client-authentication-module`) and whose value is a plain HTTPS URL to a non-registry host (`https://repo.securityctrl.com/ir-annuities-client-authentication-module`) instead of a semver range. On `npm install`, npm fetches whatever bytes that URL currently returns and installs them as this dependency, with no version pin, no integrity hash, and no registry provenance; any lifecycle scripts contained in the fetched artifact execute on the installer. The dependency key matching the package's own name creates a dependency-confusion shape that can win resolution against an internal package of the same name. The shipped index.js is an inert stub, so the manifest itself is the delivery mechanism — the absence of local scripts does not prevent the fetch or its lifecycle execution.\n\nAny computer that has this package installed or running should be considered fully compromised.
