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. The credential mirroring appears to support the Jcode integration, and I found no evidence that the credentials are exfiltrated to an unrelated service. However, it automatically exposes credentials from several other AI clients to the Jcode agent without a per-credential opt-in, which is a meaningful capability risk. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-11-03T03:58:46.399Z - **Finished:** 2026-11-03T04:00:14.248Z - **Download time:** 507 ms - **Static scan time:** 4944 ms - **AI review time:** 82397 ms - **Total time:** 87849 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 host automatically makes discovered local AI-client credentials available to the Jcode agent. - **Trigger:** Starting the package’s host-mode Jcode peer. - **Impact:** The Jcode agent may be able to act using accounts configured for other AI clients. The inspected source does not establish that credentials are transmitted to Cotal. - **Evidence paths:** dist/host.js, .lpm-dependency-evidence-91067eee-890d-4e4e-bb49-93d25f049020/0/npm-linux/dist/launch.js - **Review source:** ai\_review - **Reviewed:** 2026-11-03T04:00:14.248Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The host scans known Jcode and other AI-client credential locations and mirrors found files into a private Jcode home before launching the Harness API bridge. - **Rationale:** The credential mirroring appears to support the Jcode integration, and I found no evidence that the credentials are exfiltrated to an unrelated service. However, it automatically exposes credentials from several other AI clients to the Jcode agent without a per-credential opt-in, which is a meaningful capability risk. - **Files touched:** .claude/.credentials.json, .codex/auth.json, .gemini/oauth\_creds.json, .cursor/auth.json, .config/github-copilot/hosts.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The package describes itself as a Cotal host-mode mesh peer driven through Jcode’s Harness API bridge., The credential inventory includes local Claude, Codex, Gemini, Cursor, and GitHub Copilot credential stores., When the host starts, it calls mirrorJcodeCredentials for the per-agent Jcode home., That function copies or links the discovered credential files into the Jcode home., The Jcode instance is launched with inheritLogins:false, but only after the connector has mirrored credentials., The manifest’s scripts list contains typecheck, test, build, and bundle; it declares no install lifecycle hook. - **Evidence against:** The credential handling is part of the package’s Jcode host integration, and the files are prepared for a local Jcode instance., The inspected code does not establish that these credentials are sent to Cotal or another unrelated host., The Jcode launcher’s separate credential-inheritance option is disabled. ## Affected versions and remediation This report applies to @cotal-ai/connector-jcode@0.135.12. - Review the evidence and your use of @cotal-ai/connector-jcode@0.135.12 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.
