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. The high-risk detections resolve to normal bundled browser functionality: a pinned PDF renderer import, authenticated SDK requests, and base64 byte handling. The package has no automatic registry install hook or concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-03T21:55:46.020Z - **Finished:** 2026-09-03T21:59:52.356Z - **Download time:** 6149 ms - **Static scan time:** 45645 ms - **AI review time:** 194542 ms - **Total time:** 246336 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 was established. Runtime network use is limited to visible product functionality and a pinned PDF viewer dependency. - **Trigger:** Using Feathery form or assistant features, including PDF rendering. - **Impact:** No concrete unauthorized execution, persistence, credential theft, or exfiltration was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-03T21:59:52.356Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Authenticated Feathery API requests and a pinned PDF.js dynamic import. - **Rationale:** The high-risk detections resolve to normal bundled browser functionality: a pinned PDF renderer import, authenticated SDK requests, and base64 byte handling. The package has no automatic registry install hook or concrete malicious behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest declares a publication build hook, not a preinstall, install, or postinstall hook., The PDF loader dynamically imports a pinned pdfjs module from jsDelivr at runtime., The main browser bundle reads a Feathery session cookie and sends it as an API request header., The semantic-limit artifact is a CommonJS bundle that imports the primary implementation., The AssistantChat artifact decodes base64 chunks into byte arrays for a queued segment., The reported new artifact starts with ordinary React and UI module imports. - **Evidence against:** No automatic registry install hook or self-dependency was found., The PDF import is a visible, version-pinned dependency load for PDF rendering., The AssistantChat base64 operation creates bytes and queues them; it does not evaluate decoded content., The cookie use is explicit SDK authentication for the request URL, not collection sent to an unrelated endpoint., No source evidence established credential harvesting, shell execution, persistence, destructive behavior, or covert exfiltration. ## Affected versions and remediation This report applies to @feathery/react@2.87.0. - Review the evidence and your use of @feathery/react@2.87.0 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.
