Do not edit below this line.=-_\n\n## Source: amazon-inspector (cc68c81374c5b78e36fea2f599c5e0004ead6e56dfd02b40cec4f73c62193b30)\nThe package presents itself as a Tailwind CSS forms plugin (README, repository field, and installation docs are copied verbatim from @tailwindcss/forms) but its sole main module src/index.js is a heavily obfuscator.io-obfuscated Node loader with no CSS-plugin functionality. On require(), the module executes top-level code that installs a createRequire and publishes require, module, and global into named globals (global.r, global.m, global.i, plus several _H/_t_u/_t_s handles) and imports spawn from node:child_process — a stager shape that hands arbitrary execution primitives to code assembled from the rotating string array. It also enumerates public Ethereum JSON-RPC endpoints (drpc.org, publicnode.com, blockscout, blastapi.io) and an Etherscan-like indexer, calls eth_blockNumber / eth_getBlockByNumber / eth_getTransactionCount, and pulls the transaction list for a hardcoded 42-character Ethereum address 0xa322E5f39aDC2490Ef6f0121063eD311D3080e1a, using the returned data as C2 signalling. Results are POSTed with a custom X-Payload-* header to an external endpoint reconstructed from string-array fragments ending in ut.com/api. A CSS plugin has no legitimate reason for obfuscation, node:child_process, or Ethereum RPC traffic; the cover story does not match the shipped code, and the payload runs the moment a developer requires the package.\n","state":0,"publishedAt":"2026-09-10T18:05:11+00:00","modifiedAt":"2026-09-14T16:32:03.5135789+00:00","affected":[{"ecosystem":"npm","name":"tailwindcss-contact-forms","ranges":[],"versions":["0.5.8","0.5.6","0.5.5","0.5.4","0.5.9","0.6.0","0.5.7","0.6.1","0.6.2"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/tailwindcss-contact-forms/v/0.5.8","https://www.npmjs.com/package/tailwindcss-contact-forms/v/0.5.6","https://www.npmjs.com/package/tailwindcss-contact-forms/v/0.5.5","https://www.npmjs.com/package/tailwindcss-contact-forms/v/0.5.4","https://www.npmjs.com/package/tailwindcss-contact-forms/v/0.5.9","https://www.npmjs.com/package/tailwindcss-contact-forms/v/0.6.0","https://www.npmjs.com/package/tailwindcss-contact-forms/v/0.5.7","https://www.npmjs.com/package/tailwindcss-contact-forms/v/0.6.1","https://www.npmjs.com/package/tailwindcss-contact-forms/v/0.6.2"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-16124","license":"OSV · upstream source license applies","key":"osv:MAL-2026-16124","identifiers":["MAL-2026-16124"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
