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-2026-10078/ (Markdown: https://insights.sbomify.com/MAL-2026-10078/index.md)","id":"MAL-2026-10078","markdown":"https://insights.sbomify.com/MAL-2026-10078/index.md","name":"MAL-2026-10078","record":{"aliases":["GHSA-cwcf-rmgg-qg9w"],"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 postinstall lifecycle script that runs `id` and reads the process environment, piping the collected host identity and environment variables to a remote endpoint via curl.
