Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Static review of the manifest and every high-severity flagged file shows a React form widget talking to Feathery and known vendors, with prepare limited to husky and no install hook. Scanner labels such as eval, remote decode-execute, session hijack, and obscured URLs are noisy matches on pdf.js loading, audio atob, FingerprintJS, and datepicker CSS. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-17T05:12:40.020Z - **Finished:** 2026-09-17T05:16:28.781Z - **Download time:** 1276 ms - **Static scan time:** 27422 ms - **AI review time:** 200062 ms - **Total time:** 228761 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:** This published package is a Feathery React form SDK. High-risk scanner matches are first-party API URLs, CDN-loaded pdf.js and voice models, FingerprintJS selector decoding, and a datepicker bundle, not a hidden attack. npm install does not run a payload. - **Trigger:** A consumer installs the library and imports it to render Feathery forms in a browser app. - **Impact:** No confirmed malicious impact; form and analytics traffic stay on product-aligned backends when the SDK is used. - **Review source:** ai\_review - **Reviewed:** 2026-09-17T05:16:28.781Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Browser form SDK with vendor CDN helpers - **Rationale:** Static review of the manifest and every high-severity flagged file shows a React form widget talking to Feathery and known vendors, with prepare limited to husky and no install hook. Scanner labels such as eval, remote decode-execute, session hijack, and obscured URLs are noisy matches on pdf.js loading, audio atob, FingerprintJS, and datepicker CSS. ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json scripts include prepare and prepublishOnly, not install-time hooks, pdf.js is loaded with new Function wrapping import of a jsDelivr ESM URL, AssistantChat base64-decodes audio chunks and loads VAD and ONNX assets from jsDelivr, FingerprintJS atob-decodes ad-blocker CSS selectors; form traffic targets Feathery API hosts, the CJS field bundle is ordinary React requires plus a country-flag font polyfill, a large datepicker style chunk was added; it is react-datepicker CSS, not a payload - **Evidence against:** There is no preinstall, install, or postinstall script; prepare runs husky and prepublishOnly runs yarn build, No bin entry, no self-dependency, and no child\_process or remote-text eval, Dynamic Function only hides import(url) so bundlers do not rewrite the pdf.js CDN specifier, atob usage is TTS/audio bytes and FingerprintJS selector strings, not a hidden command-and-control URL, Network hosts match the Feathery form product plus Stytch, Stripe, Segment, and pinned jsDelivr libraries ## Affected versions and remediation This report applies to @feathery/react@2.81.0. - Review the evidence and your use of @feathery/react@2.81.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
