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. Scanner labels matched bundled pdf.js import, FingerprintJS, ONNX voice-activity code, and audio base64 decode inside a normal Feathery React SDK. There is no install-time mutation or concrete malicious chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-16T17:10:30.805Z - **Finished:** 2026-09-16T17:15:25.480Z - **Download time:** 2306 ms - **Static scan time:** 31090 ms - **AI review time:** 261278 ms - **Total time:** 294675 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 Feathery React form SDK has no registry install hooks that mutate a consumer project. Runtime PDF loading, device fingerprinting, voice models, and audio decode are product features of the form and assistant UI, not a hidden payload. - **Trigger:** An application installs the package from the npm registry and renders Feathery form or assistant components. - **Impact:** No confirmed supply-chain attack; integrating apps talk to Feathery and listed third-party widgets. - **Review source:** ai\_review - **Reviewed:** 2026-09-16T17:15:25.480Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-invoked React form and assistant SDK - **Rationale:** Scanner labels matched bundled pdf.js import, FingerprintJS, ONNX voice-activity code, and audio base64 decode inside a normal Feathery React SDK. There is no install-time mutation or concrete malicious chain. ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** PDF viewer loads pdfjs-dist from jsdelivr with new Function wrapping import., Assistant chat decodes base64 into audio bytes for playback., Bundled FingerprintJS uses atob on ad-block selectors and probes google.com/generate\_204., Voice-activity code dynamically imports a same-origin ONNX worker blob., A newly added chunk is react-datepicker UI, not a payload., A large CJS file the scanner could not fully analyze is a country-flag font polyfill and timezone tables. - **Evidence against:** No preinstall, install, or postinstall scripts; prepare is husky and prepublishOnly is yarn build., Manifest describes a React Feathery form library and publishes only dist, cjs, and umd., Network use matches Feathery APIs and declared integrations such as Stripe, Stytch, and analytics., FingerprintJS, VAD, pdf.js, and audio decode match listed dependencies and product features., No obfuscated malware, secret theft, self-dependency install chain, or agent-config writes. ## Affected versions and remediation This report applies to @feathery/react@2.82.1. - Review the evidence and your use of @feathery/react@2.82.1 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.
