Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 15 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 2.89.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. No concrete malicious behavior was confirmed, but runtime execution of a remotely served JavaScript module without integrity verification remains an unresolved security risk. The scanner's claimed decoded-payload behavior was not supported by the inspected decode path. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-09-13T01:49:15.979Z - **Finished:** 2026-09-13T01:52:05.347Z - **Download time:** 1272 ms - **Static scan time:** 24405 ms - **AI review time:** 143691 ms - **Total time:** 169368 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:** At browser runtime, PDF functionality downloads and dynamically imports pdf.js from jsDelivr. This permits remotely served code to run if that CDN asset is compromised or altered. - **Trigger:** A consumer renders functionality that loads the PDF helper or assistant attachment PDF support. - **Impact:** A compromised remote asset could execute in the consuming application's browser origin. - **Evidence paths:** dist/fthry\_pdfjsLoader.CRkrFcJY.js, umd/AssistantChat.f564585b8f044e96f031.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T01:52:05.347Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Dynamic import of remotely hosted JavaScript. - **Rationale:** No concrete malicious behavior was confirmed, but runtime execution of a remotely served JavaScript module without integrity verification remains an unresolved security risk. The scanner's claimed decoded-payload behavior was not supported by the inspected decode path. - **Files touched:** dist/fthry\_pdfjsLoader.CRkrFcJY.js, umd/AssistantChat.f564585b8f044e96f031.js - **Network endpoints:** cdn.jsdelivr.net ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The browser bundles construct dynamic imports for JavaScript served from a remote CDN., The remotely imported pdf.js code is not integrity-pinned in the package artifact. - **Evidence against:** package.json has no npm preinstall, install, or postinstall hook., The prepare hook is a Husky development hook, while prepublishOnly only builds the package., The observed Base64 decode is for audio bytes, not decoded code execution., No credential harvesting, filesystem access, shell execution, or covert endpoint was confirmed. ## Affected versions and remediation This report applies to @feathery/react@2.89.0. - Review the evidence and your use of @feathery/react@2.89.0 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.
