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. Source inspection shows a browser React library with explicit runtime extension/rendering features, not malicious install-time or covert data-handling behavior. Scanner signals arise from bundled dependencies and intended dynamic browser functionality. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-05T20:43:57.005Z - **Finished:** 2026-08-05T20:45:04.639Z - **Download time:** 1263 ms - **Static scan time:** 25844 ms - **AI review time:** 40525 ms - **Total time:** 67634 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. Runtime dynamic loading supports configured custom fields and PDF rendering, not automatic package compromise. - **Trigger:** A host application explicitly renders a custom field or PDF/chat feature. - **Impact:** Host-provided custom code may run in its intended iframe context; no unconsented installation-time or credential-exfiltration chain was found. - **Evidence paths:** package.json, dist/fthry\_index.yO8J-w4n.js, dist/fthry\_AssistantChat.XzRCZRiU.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T20:45:04.639Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-configured browser component execution and pinned CDN module import. - **Rationale:** Source inspection shows a browser React library with explicit runtime extension/rendering features, not malicious install-time or covert data-handling behavior. Scanner signals arise from bundled dependencies and intended dynamic browser functionality. - **Files touched:** package.json, cjs/index.js, dist/fthry\_index.yO8J-w4n.js, dist/fthry\_AssistantChat.XzRCZRiU.js, dist/fthry\_index.D1WKUEU6.js, umd/CustomField.895d9a1d34e8e7b8b8d0.js ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** dist/fthry\_index.yO8J-w4n.js builds an iframe that compiles and imports user-supplied custom React component code., dist/fthry\_AssistantChat.XzRCZRiU.js uses new Function only to dynamically import pinned pdfjs-dist CDN modules. - **Evidence against:** package.json has no preinstall/install/postinstall hook; prepare only invokes husky., No child\_process, Node filesystem, credential harvesting, or exfiltration behavior found in distributed JS., Custom-field network imports and code execution are runtime features driven by configured component code, not install/import-time behavior., The flagged WOFF2 is a font asset; no executable payload was identified. ## Affected versions and remediation This report applies to @feathery/react@2.66.0. - Review the evidence and your use of @feathery/react@2.66.0 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.
