Source: amazon-inspector (a1083ea1ddf83f29a443e7ba4b24db0d24da35dfd0a9d0ac032ae20501ac57ea) npm package tailwind-forms-kit@0.5.1 impersonates the @tailwindcss/forms plugin: the package.json name field is ' tailwind-forms-kit' (with a leading space), the README mirrors tailwindlabs/tailwindcss-forms, and the repository field points at the legitimate tailwindlabs/tailwindcss-forms repo. The shipped src/index.js (the package's main entry) is not a Tailwind plugin. It is a single-line obfuscator.io-obfuscated loader (string array _0x18ab with 303 entries, rotate/shift IIFE, decoder _0x35ba, hex-named variables) that at require() time imports node:http, node:https, node:zlib, and spawn from node:child_process. It reassembles at runtime a hardcoded Ethereum sender address (0xa322E5f39aDC2490EfD311D3080e6f0121063e1a) and a list of public Ethereum RPC endpoints and an Etherscan-style indexer URL (publicnode.com, 1rpc.io,…

# Patch Next advisory brief: GHSA-cpgv-j9j3-hc97

Advisory: Malicious code in tailwind-forms-kit (npm)
IDs: GHSA-cpgv-j9j3-hc97
Record: https://patchnext.com/advisories/mal-2026-17310 (revision 1, source checked 4 Nov 2026, 06:00 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm tailwind-forms-kit: affected every version

## Suggested inspection (read-only)
- `npm ls tailwind-forms-kit --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on tailwind-forms-kit.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
