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. Inspected source shows service-session credential forwarding to a caller-selected destination without an enforced destination restriction on that credential. This warrants a warning for dangerous capability, while the evidence does not support malicious intent or publication blocking. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-01T16:38:06.368Z - **Finished:** 2026-10-01T16:41:31.615Z - **Download time:** 2553 ms - **Static scan time:** 30602 ms - **AI review time:** 172092 ms - **Total time:** 205247 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:** The exported assistant can forward an existing Feathery session credential to a caller-selected origin. This establishes conditional credential exposure, without evidence of a covert recipient or malware intent. - **Trigger:** A caller supplies an unrelated baseUrl, omits getJwt, and opens the assistant while a Feathery session cookie exists. - **Impact:** The configured endpoint could receive the Feathery session credential if the browser permits the request. - **Evidence paths:** dist/index.js, dist/fthry\_AssistantChat.DAealcHs.js, cjs/fthry\_index.KGNViWmn.js - **Review source:** ai\_review - **Reviewed:** 2026-10-01T16:41:31.615Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The assistant copies the cookie into X-Feathery-Session and sends it with thread requests derived from baseUrl; the request wrapper does not remove caller-provided headers for unrelated origins. - **Rationale:** Inspected source shows service-session credential forwarding to a caller-selected destination without an enforced destination restriction on that credential. This warrants a warning for dangerous capability, while the evidence does not support malicious intent or publication blocking. ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The public entrypoint exports AssistantChat, which accepts a caller-selected baseUrl., Without getJwt, AssistantChat reads the existing Feathery session cookie and adds it to request headers., Thread requests use the supplied baseUrl origin and send those headers through fetch., Opening the assistant activates thread fetching; supplying getJwt bypasses the cookie-based header branch., The request wrapper returns existing options unchanged for destinations outside its backend origin check. - **Evidence against:** The built-in form caller selects the Feathery API origin., The inspected dynamic loader fetches a pinned PDF renderer for document previews; no concrete malware behavior was identified. ## Affected versions and remediation This report applies to @feathery/react@2.102.0. - Review the evidence and your use of @feathery/react@2.102.0 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.
