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-2026-4622/ (Markdown: https://insights.sbomify.com/MAL-2026-4622/index.md)","id":"MAL-2026-4622","markdown":"https://insights.sbomify.com/MAL-2026-4622/index.md","name":"MAL-2026-4622","record":{"aliases":["GHSA-74x9-35vr-vx9c"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require, index.js invokes initPlugin() at the module top level, which performs an HTTPS GET to https://jsonkeeper.com/b/VL3WY, parses the response JSON, and passes the 'cookie' field to new Function.constructor('require', body)(require). This compiles attacker-controlled JavaScript and invokes it with the installer's `require`, granting arbitrary code execution with full Node.js privileges on every import. The payload host (jsonkeeper.com) is an anonymous paste service whose contents are mutable, so the executed code can change at any time without a package update. The package is also a typosquat of the widely-installed `normalize-path`: it impersonates the original author (Jon Schlinkert) in package.json and mimics the normalizePath API surface to lure consumers who mistype the dependency name.\n\nAny computer that has this package installed or running should be considered fully compromised.
