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. Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-06T21:54:31.835Z - **Finished:** 2026-10-06T21:55:23.005Z - **Download time:** 1275 ms - **Static scan time:** 1416 ms - **AI review time:** 48478 ms - **Total time:** 51170 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:** Managed launches configure OpenCode to allow all permissions and load the Cotal plugin. This is a concrete agent capability risk, but no active malicious attack was established. - **Trigger:** A caller invokes the connector's launch builder and starts the returned server command. - **Impact:** The managed agent can perform tool actions without ordinary permission prompts within that session. - **Evidence paths:** dist/index.js, dist/serve.js, dist/plugin/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-06T21:55:23.005Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The builder places permissive agent configuration in OPENCODE\_CONFIG\_CONTENT, which the shim passes to OpenCode. - **Rationale:** Source inspection establishes explicit launch-time agent configuration that removes permission prompts, warranting a capability warning under the supplied policy. It does not establish malicious intent, install-hook abuse, or a reverse shell. - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The launch builder enables all OpenCode permissions and loads the bundled plugin., The configuration is passed through the launch environment to the server shim., The shim starts an authenticated OpenCode server on loopback., The plugin stays inactive outside an identified managed session., package.json has build and development scripts but no install lifecycle hooks. - **Evidence against:** No concrete malware behavior or reverse shell was identified., The indicated agent integration location is bundled documentation, not a configuration write., The inspected configuration applies to a launched session rather than an install-time modification of global agent settings. ## Affected versions and remediation This report applies to @cotal-ai/connector-opencode@0.69.0. - Review the evidence and your use of @cotal-ai/connector-opencode@0.69.0 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.
