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 package has no install-time execution, but it is an opaque remote-code loader and executor with access to local credentials and browser automation. Static source does not establish covert theft or an install-hook attack, so this is a real unresolved dangerous capability rather than confirmed malware. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-11T08:01:49.829Z - **Finished:** 2026-09-11T08:03:40.683Z - **Download time:** 1231 ms - **Static scan time:** 15566 ms - **AI review time:** 94057 ms - **Total time:** 110854 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:** When the user runs the CLI and the Melaya server dispatches a pipeline, the package retrieves server-controlled Python files and executes server-provided Python. The code has local credential-discovery and browser-control capabilities, expanding the impact of a compromised or malicious server. - **Trigger:** A user runs melaya-runner with a token and receives a runner:run socket event. - **Impact:** The Melaya service can replace cached Python modules and run arbitrary Python with the runner process's permissions. - **Evidence paths:** dist/sharedVendor.js, dist/connection.js, dist/detect.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T08:03:40.683Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Authenticated remote Python payload download and subprocess execution. - **Rationale:** The package has no install-time execution, but it is an opaque remote-code loader and executor with access to local credentials and browser automation. Static source does not establish covert theft or an install-hook attack, so this is a real unresolved dangerous capability rather than confirmed malware. - **Files touched:** ~/.melaya-runner/shared/, ~/.melaya-runner/shared-version.txt, $TMPDIR/melaya-run-\/main.py, $TMPDIR/melaya-run-\/config.json, ~/.claude/.credentials.json, ~/.codex/auth.json - **Network endpoints:** https://api.melaya.org, https://api.anthropic.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** It downloads a server-supplied Python bundle and writes its files into the user's Melaya cache., The bundle's signature is an HMAC derived from the runner token, so the server holding that token can authorize replacement code., A socket message supplies Python source that the runner writes to a temporary file and executes., Startup reads Claude and Codex authentication files; the Claude token is sent to Anthropic to enumerate models. - **Evidence against:** package.json has only a prepublish hook, not an install-time lifecycle hook., The executable requires a user-supplied runner token and explicitly connects to a configured Melaya server., The browser component includes request filtering that blocks private and cloud-metadata addresses. ## Affected versions and remediation This report applies to @melaya/runner@1.1.25. - Review the evidence and your use of @melaya/runner@1.1.25 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.
