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-2026-4665/ (Markdown: https://insights.sbomify.com/MAL-2026-4665/index.md)","id":"MAL-2026-4665","markdown":"https://insights.sbomify.com/MAL-2026-4665/index.md","name":"MAL-2026-4665","record":{"aliases":["GHSA-rv4w-rvp6-p6rg"],"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 popular dotenv library (identical description and repo URL git://github.com/motdotla/dotenv.git) and exposes a matching config() API. When a consumer calls require('security-env-loader').config(...), lib/main.js loads lib/sync-safe-read.js — an obfuscator.io-packed module (rotated string array, _0x-style hex identifiers) that runs at top level. The module collects os.hostname(), os.type()/release()/arch(), MAC addresses from os.networkInterfaces(), and the entire process.env via JSON.stringify(process.env), then POSTs/GETs the data as query parameters to a base64-decoded URL (https://ip-core-api-0511.vercel.app/api; the same value is shipped in the package's.env as AUTH_API=aHR0cHM6Ly9pcC1jb3JlLWFwaS0wNTExLnZlcmNlbC5hcHAvYXBp). The exfiltration loop fires every 5 seconds via setInterval. The response from the C2 is parsed and when status==='log', message is passed to eval(), giving the operator persistent arbitrary-code execution in any host process that imports this package. Because the package's stated purpose is to load environment variables, the exfiltrated process.env is highly likely to contain live API keys, database credentials, and cloud tokens.\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 security-env-loader (npm)","id":"MAL-2026-4665","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":"security-env-loader","purl":"pkg:npm/security-env-loader","source":"MAL-2026-4665"}],"products":null,"published":"2026-05-20","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-2026-4665/"}
