Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. OpenSSF/OSV advisory MAL-2026-16262 confirms this npm version as malicious.

Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to tailwindcss-form-ui@0.5.1. - Avoid installing tailwindcss-form-ui@0.5.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% Package name and repository field impersonate the legitimate tailwindlabs/tailwindcss-forms plugin, but the shipped main entry src/index.js is a fully obfuscated (obfuscator.io string-array) module that has nothing to do with Tailwind CSS. On module load it imports node:child\_process (spawn), node:http/https, node:zlib and node:url, builds a list of Ethereum JSON-RPC endpoints (process.env.ETH\_RPC\_URL, \*.publicnode.com, drpc.org, 1rpc.io/eth, blockscout) and an Etherscan-style txlist URL for the hardcoded sender address 0xa322E5f39aDC2490EfD311D3080e6f0121063e1a, and polls eth\_blockNumber / eth\_getBlockByNumber / eth\_getTransactionCount to retrieve attacker-published transactions. The retrieved payloads are decompressed via gunzip/inflate/brotli and passed to child\_process.spawn, giving whoever controls that Ethereum address arbitrary command execution on any host that requires or imports the package. The on-chain command channel is takedown-resistant. The Tailwind-forms identity, the obfuscated main, and the require-time RCE together form a cover-story typosquat delivering installer-side remote code execution. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** tailwindcss-form-ui - **Ecosystem:** npm - **Version:** 0.5.1 - **Version published:** 2026-09-17T13:31:03.780Z - **Package first seen:** 2026-09-17T20:55:04.245Z - **Package last seen:** 2026-09-17T20:55:04.245Z - **Known versions:** 1 - **Latest version:** 0.5.1 - **Appeal under review:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]()
