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. Automatic staging of credentials from multiple unrelated tools creates a real exposure risk, and the source does not show a consent control for that transfer. I found no evidence that the copied credentials leave the local Jcode process, so this warrants a warning rather than a malicious verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-11-04T17:06:10.411Z - **Finished:** 2026-11-04T17:07:56.837Z - **Download time:** 1020 ms - **Static scan time:** 4932 ms - **AI review time:** 100473 ms - **Total time:** 106426 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 stages credentials from several other AI and coding tools into a private Jcode home. - **Trigger:** When the managed Jcode host starts and prepares its seat. - **Impact:** The launched Jcode process can access credentials belonging to other services; the inspected source does not show whether or where those credentials are transmitted. - **Evidence paths:** dist/host.js - **Review source:** ai\_review - **Reviewed:** 2026-11-04T17:07:56.837Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It inventories credential files and Cursor state from the user's home and copies them into the Jcode seat before launching the Jcode API bridge. - **Rationale:** Automatic staging of credentials from multiple unrelated tools creates a real exposure risk, and the source does not show a consent control for that transfer. I found no evidence that the copied credentials leave the local Jcode process, so this warrants a warning rather than a malicious verdict. - **Files touched:** dist/host.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The host bundles credential paths for Claude, Codex, Gemini and Cursor, including Cursor state databases., When the host prepares a Jcode seat, it calls mirrorJcodeCredentials before starting the Jcode instance., The package describes itself as a Jcode Harness API connector., The credential mirror implementation inventories credentials from the user's Jcode home, app config and external home. - **Evidence against:** The manifest has no install, preinstall or postinstall lifecycle script., The inspected code shows credentials being staged for a local Jcode instance, but does not establish that the copied credentials are transmitted to an unrelated host., The connector's stated purpose involves launching Jcode through its Harness API bridge. ## Affected versions and remediation This report applies to @cotal-ai/connector-jcode@0.141.10. - Review the evidence and your use of @cotal-ai/connector-jcode@0.141.10 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.
