Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No confirmed malicious attack surface is established. The package is a Tailwind form-styling plugin with explicit developer release helpers. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-30T01:14:21.196Z - **Finished:** 2026-09-30T01:15:06.057Z - **Download time:** 515 ms - **Static scan time:** 94 ms - **AI review time:** 44251 ms - **Total time:** 44861 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface is established. The package is a Tailwind form-styling plugin with explicit developer release helpers. - **Trigger:** Importing the package during a Tailwind build, or explicitly running a release utility. - **Impact:** Applies form-control styles; no credential collection, network transmission, persistence, or destructive action was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-30T01:15:06.057Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Generates Tailwind CSS rule objects and prints local release metadata. - **Rationale:** Direct inspection of the manifest, both scanner-flagged release scripts, and the runtime entry point found no lifecycle execution or malicious behavior. The similarity signal is not supported by the inspected source. ### Review decision - **Verdict:** Clean - **Confidence:** 99.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest has no preinstall, install, or postinstall hook; its release utilities require explicit npm-script invocation., The flagged release-notes utility only reads CHANGELOG.md and prints a selected section., The flagged release-channel utility only parses a version string and prints a channel., The runtime entry point creates Tailwind form-style rules and exports the plugin. - **Evidence against:** The release utilities reference an environment version variable, but do not transmit or persist it., The only URLs in the runtime source are SVG namespaces and comments; no network client is present. ## Affected versions and remediation This report applies to tailwindcss-form-kit@0.5.1. - Avoid installing tailwindcss-form-kit@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.
