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 shows a commercial Feathery React client with no install hooks that mutate the host, no self-dependency chain, and no decoded remote payload execution. High scanner labels map to pdf.js loading, FingerprintJS, form cookies, and a datepicker bundle. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-16T17:10:33.179Z - **Finished:** 2026-09-16T17:14:24.216Z - **Download time:** 1265 ms - **Static scan time:** 29801 ms - **AI review time:** 199971 ms - **Total time:** 231037 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 is a published Feathery React form SDK. Scanner hits come from pdf.js CDN loading, FingerprintJS, cookie helpers, and a new datepicker chunk, all consistent with the product. No install-time mutation or hidden exfiltration path was found. - **Trigger:** A consuming app installs the library and renders Feathery forms or the assistant UI. - **Impact:** No confirmed malicious impact beyond normal form, auth, analytics, and document-viewer behavior. - **Review source:** ai\_review - **Reviewed:** 2026-09-16T17:14:24.216Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Package-aligned form SDK networking and optional CDN pdf.js import - **Rationale:** Static review shows a commercial Feathery React client with no install hooks that mutate the host, no self-dependency chain, and no decoded remote payload execution. High scanner labels map to pdf.js loading, FingerprintJS, form cookies, and a datepicker bundle. ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** prepare and prepublishOnly scripts exist, but they are husky and yarn build, not install hooks., PDF loader uses new Function only to dynamically import pinned pdf.js from jsdelivr., Assistant chat uses the same CDN import helper and atob on audio bytes., Main bundle includes FingerprintJS Base64 CSS selectors, cookie helpers, and Feathery API URLs., CJS entry re-exports the form SDK and regional api.feathery.io hosts., A large datepicker chunk is new versus a prior stored version. - **Evidence against:** No preinstall, install, or postinstall scripts; published files are dist, cjs, and umd., Network targets are Feathery APIs/CDNs plus form integrations such as pdfjs-dist on jsdelivr., new Function only returns import(u) for a version-pinned pdf.min.mjs URL., atob is used for FingerprintJS ad-block selectors, image data URLs, and voice audio, not to run decoded code., Cookie reads are named SDK session helpers, not a hidden account-takeover path., No self-dependency, child\_process, eval, or install-time agent/config mutation. ## Affected versions and remediation This report applies to @feathery/react@2.82.0. - Review the evidence and your use of @feathery/react@2.82.0 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.
