On require(), the module attaches require and module to global scope, then queries Ethereum JSON-RPC endpoints (eth.publicnode.com, 1rpc.io/eth, eth-mainnet.public.blastapi.io, eth.drpc.org) and Etherscan/Blockscout txlist APIs for transactions from the hardcoded sender address 0xa322E5f39aDC2490EfD311D3080e6f0121063e1a, decompresses the returned transaction data (gzip/deflate/brotli), and passes it to code-construction and node:child_process.spawn sinks. The hardcoded sender's on-chain transactions are a mutable, attacker-controlled payload channel (EtherHiding pattern), granting arbitrary code execution on any installer that require()s the module.\n","affected":[{"package":{"ecosystem":"npm","name":"tailwindcss-forms-ui"},"versions":["0.5.2"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"src/index.js","sha256":"fd1ef3edfc6c02581abf6bf69f9e73b19ca8d3ddc915fa51beba648e6c0ae62f","tlsh":"e103e9957e81121a33434f7fba1bf4e4e12a1899369448c7d21cbc94f8e631ae9f6d34"}],"package_integrity":[{"filename":"tailwindcss-forms-ui-0.5.2.tgz","hashes":{"sha1":"098bbab02e9ff93deea3d16cf896658488c0b950","sha512_sri":"sha512-0Ms4seAbUY3cYwuQo0xrWoxBemzYpqwWF+7CCUwan1NXmTe1XmvYSuGWZaGf9Wwex4Bdnv7MhwNxkNvNrDLLEw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/tailwindcss-forms-ui/v/0.5.2"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-020188","import_time":"2026-09-18T20:38:13.863251763Z","modified_time":"2026-09-18T20:25:14Z","sha256":"6f2bdfef8937b1e6ef4979181693e00adbdfbe7521b8b240268f76beff8b3be8","source":"amazon-inspector","versions":["0.5.2"]}]}}
