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-2026-5692/ (Markdown: https://insights.sbomify.com/MAL-2026-5692/index.md)","id":"MAL-2026-5692","markdown":"https://insights.sbomify.com/MAL-2026-5692/index.md","name":"MAL-2026-5692","record":{"aliases":["GHSA-22wq-6mfh-69qv"],"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 executes a harvest-and-exfiltrate chain against the installer's machine. It reads files under /app, /root, and /flag.txt, shells out via `execFileSync('/bin/sh', ['-c',...])` to recursively grep the filesystem for `HTB{...}` flag patterns and collect git history, gathers host identifiers (uid, cwd, hostname), and transmits the collected data via HTTP PUT to a hardcoded attacker endpoint at http://154.57.164.82:31250/api/modules/ECT-*. The script includes sandbox-evasion gating that exits cleanly when cwd contains `/tmp/npm-safe` or `/tmp/pkg`, or when hostname matches `nijin`, `hetzner`, or `ec2.internal` — ensuring the malicious path only fires on real installer machines. The combination of unconditional filesystem read, hardcoded non-registry IP destination, and scanner-evasion logic is an unambiguous supply-chain attack.\n\nAny computer that has this package installed or running should be considered fully compromised.
