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 require() the module opens HTTP(S)/zlib streams to Ethereum RPC endpoints (public.blockscout, *.drpc.org, *.publicnode.com) and an etherscan-like transaction indexer, queries transactions for the hardcoded address 0xa322E5f3D311D3080e9aDC2490Ef6f0121063e1a, imports node:child_process spawn, and injects reconstructed strings into the Node global object (`_t_u`, `_t_s`, `_H`, `_H2`, `_r`=require, `_m`=module, `_global`=global). This is an EtherHiding-style loader that pulls executable payload data from attacker-controlled on-chain storage and hands it to child_process/global-eval sinks, producing arbitrary code execution on the machine that requires the package (e.g. from tailwind.config.js during a build). The package name and the package.json repository field pointing at tailwindlabs/tailwindcss-forms are impersonation of the real @tailwindcss/forms plugin to induce installation.\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 tailwind-forms-styles (npm)","id":"MAL-2026-16195","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":"tailwind-forms-styles","purl":"pkg:npm/tailwind-forms-styles","source":"MAL-2026-16195"}],"products":null,"published":"2026-09-15","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-2026-16195/"}
