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-2026-5685/ (Markdown: https://insights.sbomify.com/MAL-2026-5685/index.md)","id":"MAL-2026-5685","markdown":"https://insights.sbomify.com/MAL-2026-5685/index.md","name":"MAL-2026-5685","record":{"aliases":["GHSA-636m-vpq6-g454"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On npm install, postinstall.js walks /, /app, /home, /opt, /root for files whose names match /flag|secret|env/i, reads their contents, scrapes process.env (including HOME, INIT_CWD, npm_config_registry, all env keys, and hostname), and PUTs the collected data as a YAML manifest over plaintext HTTP to the hardcoded endpoint http://154.57.164.80:30543/api/modules/ECT-987654 (and ECT-472839).
