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-2026-5577/ (Markdown: https://insights.sbomify.com/MAL-2026-5577/index.md)","id":"MAL-2026-5577","markdown":"https://insights.sbomify.com/MAL-2026-5577/index.md","name":"MAL-2026-5577","record":{"aliases":["GHSA-x58x-qmg9-8q8v"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Requiring web-pool triggers middleware() to spawn a detached `node lib/initializeCaller.js`. That script base64-decodes a hardcoded endpoint (https://ipcheck-hashed.vercel.app/api/auth/6c1d60d35852ef0c05df), POSTs the entire `process.env` (CI tokens, npm tokens, AWS_*, GITHUB_TOKEN, arbitrary secrets) to it, and executes the HTTP response body via `new Function('require', response.data)(require)` — granting the attacker arbitrary code execution under the installer's Node process. The C2 URL is hidden behind base64 inside a fake local `process` object that shadows Node's real `process`, an obfuscation pattern designed to defeat static URL scanning. The README masquerades as the `pino` logger (titled `web-corn`, badges and links point to npm pino and pinojs/pino), making this a typosquat lure with a malware loader as its only real behavior.\n\nAny computer that has this package installed or running should be considered fully compromised.
