Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Importing the package main entry executes concealed code before exporting the Tailwind form plugin. That code fetches a staged payload, executes it, launches a detached process, and removes its own loader. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T13:18:30.305Z - **Finished:** 2026-09-11T13:19:23.162Z - **Download time:** 252 ms - **Static scan time:** 87 ms - **AI review time:** 52517 ms - **Total time:** 52857 ms The recorded confidence comes from the underlying analysis.

That code fetches a staged payload, executes it, launches a detached process, and removes its own loader. - **Trigger:** Importing or requiring tailwind-form-kit, including through the supplied Tailwind configuration. - **Impact:** Arbitrary code supplied by the remote payload can run in the consumer environment and persist outside the importing process. - **Evidence paths:** package.json, src/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T13:19:23.162Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote payload retrieval followed by eval and detached process execution. - **Attack narrative:** The package declares src/index.js as its main entry. On import, concealed code runs immediately, derives remote addresses, retrieves a payload, evaluates it, and launches another Node process detached from the caller. It then rewrites src/index.js to strip the loader, concealing the behavior after the first execution. This is unrelated to a Tailwind form plugin and provides a direct staged remote-code-execution path. - **Rationale:** The import-time loader combines remote payload execution, detached process creation, and self-removal. These behaviors are concrete malicious execution, even though npm lifecycle hooks are absent. - **Files touched:** src/index.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The declared main entry loads an obfuscated import-time payload before the form plugin., The payload obtains remote content, passes it to eval, and starts a detached Node process., The entry rewrites itself after running, removing the leading payload code. - **Evidence against:** package.json contains no npm preinstall, install, or postinstall hook. ## Affected versions and remediation This report applies to tailwind-form-kit@0.6.4. - Avoid installing tailwind-form-kit@0.6.4. 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.
