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. This is an explicit but high-risk remote execution agent rather than an install-time malware chain. The code establishes a real service-controlled execution surface and local credential access, but static source does not show automatic installation abuse or unrelated secret exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-11T08:11:58.635Z - **Finished:** 2026-09-11T08:13:25.304Z - **Download time:** 765 ms - **Static scan time:** 1011 ms - **AI review time:** 84893 ms - **Total time:** 86669 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 package is a remote pipeline executor. After the user starts it with a runner token, the connected service can supply Python files and run code on the user's machine. - **Trigger:** The user runs melaya-runner with a runner token and the service sends a runner:run command. - **Impact:** A compromised or malicious service controlling the runner token can execute arbitrary Python with the user's permissions and access locally available credentials. - **Evidence paths:** dist/sharedVendor.js, dist/connection.js, dist/detect.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T08:13:25.304Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote code delivery and local Python execution. - **Rationale:** This is an explicit but high-risk remote execution agent rather than an install-time malware chain. The code establishes a real service-controlled execution surface and local credential access, but static source does not show automatic installation abuse or unrelated secret exfiltration. - **Files touched:** ~/.melaya-runner/shared/\*\*, tmpdir()/melaya-run-${runId}/main.py, tmpdir()/melaya-run-${runId}/config.json, ~/.claude/.credentials.json, ~/.codex/auth.json, ~/.config/github-copilot/apps.json, ~/.config/github-copilot/hosts.json - **Network endpoints:** api.melaya.org, api.github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The runner downloads a server-selected Python bundle and writes its files into the user's Melaya cache., A socket command writes server-provided Python into a temporary main.py for execution., The bundle and run-code signatures use a key derived from the runner token, so they do not establish an independent code-publisher trust boundary., On startup it reads local Claude, Codex, and Copilot credential sources; the Copilot token is sent to GitHub. - **Evidence against:** package.json has only a prepublish hook, not an install-time lifecycle hook., Execution requires an explicit CLI invocation with a required runner token., No source evidence shows secret exfiltration to an unrelated host or automatic execution on package installation. ## Affected versions and remediation This report applies to @melaya/runner@1.1.29. - Review the evidence and your use of @melaya/runner@1.1.29 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.
