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-2026-16124 confirms this npm version as malicious. The 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... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-09-10T19:00:05.466Z - **Finished:** 2026-09-10T19:00:05.466Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. 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-contact-forms@0.5.7. The same advisory and Firewall decision cover these 9 recorded versions: 0.5.4, 0.5.5, 0.5.6, 0.5.7, 0.5.8, 0.5.9, 0.6.0, 0.6.1, 0.6.2. - Avoid installing tailwindcss-contact-forms@0.5.7. 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% The 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. ## 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-contact-forms - **Ecosystem:** npm - **Version:** 0.5.7 - **Version published:** 2026-09-10T12:29:09.594Z - **Package first seen:** 2026-09-07T20:41:51.452Z - **Package last seen:** 2026-09-14T16:40:04.634Z - **Known versions:** 11 - **Latest version:** 0.0.1-security - **Appeal under review:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
