Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — The recipient can receive and potentially use the embedding page's token; the source shows no recipient-specific consent or destination validation. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 1.0.4 - **Selected version is latest:** Yes - **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: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The active chat and supporting request paths disclose the embedding page's cookie token to a package-selected external recipient. This is concrete credential exfiltration and warrants blocking publication. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-20T02:24:12.988Z - **Finished:** 2026-10-20T02:24:44.652Z - **Download time:** 1546 ms - **Static scan time:** 676 ms - **AI review time:** 29440 ms - **Total time:** 31664 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 chat component reads a \`token\` cookie from the embedding page and forwards it to a fixed external service host. This exposes the page's credential to a recipient selected by the package. - **Trigger:** The component loads agent details or a user sends a chat message or submits feedback. - **Impact:** The recipient can receive and potentially use the embedding page's token; the source shows no recipient-specific consent or destination validation. - **Evidence paths:** package.json, dist/index.esm.js - **Review source:** ai\_review - **Reviewed:** 2026-10-20T02:24:44.652Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Its request helpers read \`document.cookie\` and attach the token as a bearer credential to requests sent to the hardcoded host. - **Attack narrative:** When the exported chat component requests agent details, sends a chat message, or submits feedback, it reads the embedding page's \`token\` cookie and sends it as a bearer credential to a fixed external host. The package selects that recipient, and the inspected source shows no recipient-specific consent or destination validation. This is credential exposure during ordinary component use. - **Rationale:** The active chat and supporting request paths disclose the embedding page's cookie token to a package-selected external recipient. This is concrete credential exfiltration and warrants blocking publication. - **Network endpoints:** https://aitest.mxrvending.com:9097 ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package exposes the ESM bundle as its import entry point and exports the chat component., The bundle reads the page's \`token\` cookie and uses it as a bearer credential., Chat requests send that credential to a fixed package-selected host when the component sends a message., The same request helper sends the credential for agent details and feedback requests. ## Affected versions and remediation This report applies to xy-ai-chat@1.0.4. - Avoid installing xy-ai-chat@1.0.4. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 3. Critical: Hardcoded Runtime Data Exfiltration - **Category:** Source - **Confidence:** 94.0% - **Path:** dist/index.esm.js - **Public source:** [View source]() Source sends credentials or rich application records to a package-controlled external receiver enabled by default.
