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-2026-10174/ (Markdown: https://insights.sbomify.com/MAL-2026-10174/index.md)","id":"MAL-2026-10174","markdown":"https://insights.sbomify.com/MAL-2026-10174/index.md","name":"MAL-2026-10174","record":{"aliases":["GHSA-w8g3-2xjv-6vf6"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package advertises itself as a pino-style logger (exports `module.exports.pino = middleware`, keywords `fast/logger/stream/json`, pino-like file layout under lib/) but its name and behavior are unrelated to logging. When the module is loaded via require(), its middleware factory spawns a detached node child process (`spawn('node', [script,...], { detached: true, stdio: 'ignore' })`, followed by `child.unref()`) running lib/caller.js. lib/caller.js fetches a JSON document from https://json.extendsclass.com/bin/49b93b00acf1 with https://jsonkeeper.com/b/XRGF3 as fallback, extracts the `cookie` field from the response, and executes it via `new Function.constructor('require', s)` with `require` passed in, granting the fetched code full Node module access. Additional endpoints are hidden as base64-encoded strings in a fake `process` stub inside lib/caller.js and lib/const.js (`DEV_API_KEY` decoding to https://jsonkeeper.com/b/XRGF3 and https://jsonkeeper.com/b/4NAKK). The remote content is attacker-mutable paste-style hosting, and the detached/unref/stdio-ignored spawn shape conceals the loader from the parent process.\n\nAny computer that has this package installed or running should be considered fully compromised.
