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 scanner's execution signal corresponds to a transparent, pinned pdf.js CDN import used by a PDF-thumbnail component. Package lifecycle and entrypoint inspection found no install-time execution or concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 93.0% - **Started:** 2026-08-20T15:11:49.352Z - **Finished:** 2026-08-20T15:13:10.410Z - **Download time:** 1523 ms - **Static scan time:** 32104 ms - **AI review time:** 47430 ms - **Total time:** 81058 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. The flagged dynamic import is a version-pinned pdf.js dependency used for user-visible PDF thumbnail rendering. - **Trigger:** Rendering a PDF attachment thumbnail in the Assistant UI. - **Impact:** Loads the declared PDF rendering library; no credential harvesting, host mutation, or unrelated payload chain was found. - **Evidence paths:** package.json, cjs/index.js, dist/fthry\_pdfjsLoader.CRkrFcJY.js, dist/fthry\_AssistantChat.DhOtVNl3.js - **Review source:** ai\_review - **Reviewed:** 2026-08-20T15:13:10.410Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Pinned CDN import of pdf.js for PDF rendering. - **Rationale:** The scanner's execution signal corresponds to a transparent, pinned pdf.js CDN import used by a PDF-thumbnail component. Package lifecycle and entrypoint inspection found no install-time execution or concrete malicious behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 93.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** Assistant bundle dynamically imports remote pdfjs code. - **Evidence against:** Import is pinned to pdfjs-dist@5.4.296 on jsDelivr., It is invoked only by the PDF thumbnail component., No install/preinstall/postinstall hook; prepare only invokes Husky., Entrypoint imports local bundles and normal React dependencies. ## Affected versions and remediation This report applies to @feathery/react@2.77.0. - Review the evidence and your use of @feathery/react@2.77.0 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.
