@cotal-ai/connector-jcode@0.140.1
Cotal connector for Jcode: a host-mode mesh peer driven through Jcode's Harness API bridge.
AI Security Review
scanned 1d ago · by lpm-firewall-aiThe connector's purpose explains launching Jcode, but its host automatically mirrors recognized third-party credential stores and the SDK inherits logins by default. Since the inspected source does not establish where those credentials go, this is a warning-level credential-forwarding risk rather than a confirmed exfiltration attack.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
Startup of the connector host inside a Cotal managed session.
Impact
The Jcode runtime can access credentials from other AI tools and providers without a separate inheritance opt-in, creating a credential-forwarding risk whose ultimate destination is not established here.
Mechanism
The host mirrors credentials into its managed Jcode home. The SDK's default login inheritance is enabled and it launches Jcode's API bridge.
AI rationale
The connector's purpose explains launching Jcode, but its host automatically mirrors recognized third-party credential stores and the SDK inherits logins by default. Since the inspected source does not establish where those credentials go, this is a warning-level credential-forwarding risk rather than a confirmed exfiltration attack.

Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The manifest has no install, preinstall, or postinstall script; it exports the connector entry point.
- The host requires a Cotal managed-session control endpoint before it starts.
- At host startup, the connector calls `mirrorJcodeCredentials(home)` without a visible opt-in check.
- The SDK recognizes credential files from Claude, Codex, Gemini, Cursor, and other agent tools.
- The SDK inherits logins by default and launches Jcode's API bridge with the process environment.
Evidence against
- The package describes itself as a Cotal connector for Jcode, so starting Jcode and making its configured logins available are consistent with its purpose.
- The inspected source does not establish a foreign network destination receiving those credentials.
