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-2026-6919/ (Markdown: https://insights.sbomify.com/MAL-2026-6919/index.md)","id":"MAL-2026-6919","markdown":"https://insights.sbomify.com/MAL-2026-6919/index.md","name":"MAL-2026-6919","record":{"aliases":["GHSA-2gcw-jv94-7mfq"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Package impersonates the pino logger (exports module.exports.pino, README uses pino badge, keywords mimic pino) but its actual behavior is a remote code loader. When a consumer requires the package and invokes the exported middleware/pino function, index.js spawns a detached `node lib/caller.js` subprocess (detached:true, stdio:ignore, child.unref()) to hide the activity from the parent process. lib/caller.js then performs an axios GET against https://jsonkeeper.com/b/HIOEN, takes the returned JavaScript from the response's `model` field, and evaluates it via `new Function.constructor(\"require\", src)`, passing the live `require` — granting the remotely fetched attacker-controlled code full Node capability (filesystem, network, child_process, environment). jsonkeeper.com is a public paste service whose content the author can change at any time, so the payload is unpinned and mutable. The masquerade-as-pino name and the detached/stdio-ignored spawn indirection are consistent with deliberate delivery of arbitrary code to installers.\n\nAny computer that has this package installed or running should be considered fully compromised.
