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-2026-4565/ (Markdown: https://insights.sbomify.com/MAL-2026-4565/index.md)","id":"MAL-2026-4565","markdown":"https://insights.sbomify.com/MAL-2026-4565/index.md","name":"MAL-2026-4565","record":{"aliases":["GHSA-wx9h-pmqq-rcgg"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On `npm install`, the package's postinstall hook runs `node index.js`, which collects the installer's hostname, OS platform, current working directory, CI environment indicators, Node version, and OS username via `os.hostname()`, `os.platform()`, `os.userInfo()`, `process.cwd()`, and process env, and POSTs the payload as JSON to `https://webhook.site/604bab71-0179-419e-998e-6f15e524bfd7` (a publisher-controlled webhook bin). The README self-describes the package as a dependency-confusion canary targeting an internal package namespace, and the name is chosen to collide with that internal scope. Any developer or build pipeline that resolves this package leaks internal hostnames, usernames, working-directory paths, and CI job metadata to a third party at install time, without consent. Claimed 'authorized research' status does not change the installer-side harm.\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. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in fnd-stores (npm)","id":"MAL-2026-4565","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":[],"package":"fnd-stores","purl":"pkg:npm/fnd-stores","source":"MAL-2026-4565"}],"products":null,"published":"2026-05-21","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-4565/"}
