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","state":0,"publishedAt":"2026-09-18T20:25:14+00:00","modifiedAt":"2026-09-18T20:45:07.5730338+00:00","affected":[{"ecosystem":"npm","name":"tailwindcss-forms-ui","ranges":[],"versions":["0.5.2"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/tailwindcss-forms-ui/v/0.5.2"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-16295","license":"OSV · upstream source license applies","key":"osv:MAL-2026-16295","identifiers":["MAL-2026-16295"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
