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.

On `npm install`, a `preinstall` lifecycle script (preinstall.js:5-9) makes an HTTPS GET to `h5nvwrz2815ubw84cpkwhezm5db9z1nq.b.mburpcollab.com` with query parameters `package=\u003cnpm_package_name\u003e\u0026hostname=\u003cos.hostname()\u003e`, transmitting the installer's hostname off-host to a Burp Collaborator out-of-band interaction endpoint. The README states this is an authorized security test, but the code path and effect on an unsuspecting installer are identical to a hostile dependency-confusion attack: build hosts silently disclose their identity to a third-party domain during `npm install`, with no opt-in. Any build system that resolves this package (e.g., an internal Pelmorex pipeline expecting the private `@pelmnaads/naads-common-logger`) would leak hostname data.","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 @pelmnaads/naads-common-logger (npm)","id":"MAL-2026-3748","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":[],"last_affected":[],"package":"@pelmnaads/naads-common-logger","purl":"pkg:npm/%40pelmnaads/naads-common-logger","source":"MAL-2026-3748"}],"products":null,"published":"2026-05-14","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-2026-3748/"}
