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 connector's host enables credential inheritance by default, including credentials belonging to other AI tools, and stages them for a Jcode instance. This creates a meaningful credential-sharing risk, but the inspected source does not show those credentials being sent to an unrelated host, so the evidence does not support blocking as malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 79.0% - **Started:** 2026-11-03T22:01:26.735Z - **Finished:** 2026-11-03T22:02:28.543Z - **Download time:** 1768 ms - **Static scan time:** 5024 ms - **AI review time:** 55015 ms - **Total time:** 61808 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 can expose existing AI provider credentials to a Jcode instance by default. - **Trigger:** When the host launches its Jcode API bridge with login inheritance enabled (the default). - **Impact:** The Jcode instance can use credentials from other AI tools; the inspected excerpts do not establish where those credentials are subsequently sent. - **Evidence paths:** dist/host.js - **Review source:** ai\_review - **Reviewed:** 2026-11-03T22:02:28.543Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It copies or links Jcode credential files and recognized external credential files into the instance home before spawning the local bridge. - **Rationale:** The connector's host enables credential inheritance by default, including credentials belonging to other AI tools, and stages them for a Jcode instance. This creates a meaningful credential-sharing risk, but the inspected source does not show those credentials being sent to an unrelated host, so the evidence does not support blocking as malicious. - **Files touched:** ~/.jcode/auth.json, ~/.jcode/openai-auth.json, ~/.jcode/antigravity\_oauth.json, ~/.jcode/gemini\_oauth.json, ~/.jcode/google\_oauth.json, ~/.jcode/google\_credentials.json, ~/.jcode/config.toml, ~/.claude/.credentials.json, ~/.codex/auth.json, ~/.gemini/oauth\_creds.json, ~/.cursor/auth.json, ~/.config/cursor/auth.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 79.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The package describes itself as a Cotal connector that runs a Jcode Harness API bridge., The host copies or links credentials from Jcode configuration and other tools, including Claude, Codex, Gemini, and Cursor., Credential inheritance is enabled by default when the host launches the local Jcode API bridge., A separate host launch path explicitly disables login inheritance, showing that credential sharing is a configurable behavior. - **Evidence against:** There are no install lifecycle scripts in the manifest., The inspected credential flow copies or links files into a local Jcode instance home and starts a local API bridge; this review did not establish an outbound credential request. ## Affected versions and remediation This report applies to @cotal-ai/connector-jcode@0.140.0. - Review the evidence and your use of @cotal-ai/connector-jcode@0.140.0 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.
