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:** 89.0% - **Started:** 2026-10-05T05:19:35.217Z - **Finished:** 2026-10-05T05:20:51.653Z - **Download time:** 512 ms - **Static scan time:** 3966 ms - **AI review time:** 71958 ms - **Total time:** 76436 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:** Explicit agent launch injects configuration that allows permissions without approval. This establishes a dangerous agent capability, but no confirmed malicious attack. - **Trigger:** A caller invokes the connector's buildLaunch method and runs the returned command. - **Impact:** The launched agent can perform tool actions without ordinary permission approval. - **Evidence paths:** dist/index.js, dist/serve.js - **Review source:** ai\_review - **Reviewed:** 2026-10-05T05:20:51.653Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher sets permission to allow in OPENCODE\_CONFIG\_CONTENT, which the spawned OpenCode server inherits. - **Rationale:** The source supports a warning for explicit agent configuration that disables permission approvals, rather than the scanner's malware classification. There are no install lifecycle hooks, and the flagged process and socket behavior implements a local OpenCode server. - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** dist/index.js sets permission to allow and loads its plugin in the launched agent session., The launcher passes that configuration through OPENCODE\_CONFIG\_CONTENT to the serve helper., dist/serve.js starts OpenCode on 127.0.0.1 with inherited launch configuration., package.json has no automatic install lifecycle hooks., dist/plugin/index.js guards setup on an available identity. - **Evidence against:** No reverse shell or covert credential export was established; the serve helper uses a local authenticated server., The indicated agent integration locations contain embedded documentation, rather than executable configuration writes. ## Affected versions and remediation This report applies to @cotal-ai/connector-opencode@0.63.0. - Review the evidence and your use of @cotal-ai/connector-opencode@0.63.0 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.
