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. Static inspection found dangerous but package-aligned runner behavior that requires explicit CLI use and a Melaya token, with no install-time execution, persistence, destructive action, raw credential exfiltration, or AI-agent hijack. Because the package intentionally enables cloud-dispatched local code execution with weak local signature verification, warn rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-07-04T07:26:46.250Z - **Finished:** 2026-07-04T07:28:06.975Z - **Download time:** 757 ms - **Static scan time:** 325 ms - **AI review time:** 79642 ms - **Total time:** 80725 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 user-invoked Melaya local runner with remote job execution capability. It is not malicious install-time malware, but it does execute cloud-supplied Python and bootstrap remote dependencies after the user connects a runner token. - **Trigger:** Explicit execution of melaya-runner with --token, then authenticated server events - **Impact:** Melaya-controlled jobs can run locally with inherited environment, package-provided credentials, local model access, and selected local files for RAG workflows; no hidden install-time persistence or agent control-surface hijack was found. - **Evidence paths:** package.json, dist/cli.js, dist/connection.js, dist/sharedVendor.js, dist/pythonEnv.js, dist/detect.js, dist/linkedinLogin.js, dist/lumaLogin.js, dist/lumaBrowserBridge.js, dist/linkedinProxy.js - **Review source:** ai\_review - **Reviewed:** 2026-07-04T07:28:06.975Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Authenticated cloud-controlled local Python runner - **Attack narrative:** After explicit CLI startup, the runner connects to Melaya and waits for authenticated server events. Those events can cause it to download cached Python support code, build a venv, write server-provided Python/config into temp directories, and spawn it locally. This is a substantial remote execution capability, but it is the declared runner function and was not delivered through npm lifecycle execution or foreign AI-agent control-surface mutation. - **Rationale:** Static inspection found dangerous but package-aligned runner behavior that requires explicit CLI use and a Melaya token, with no install-time execution, persistence, destructive action, raw credential exfiltration, or AI-agent hijack. Because the package intentionally enables cloud-dispatched local code execution with weak local signature verification, warn rather than block. - **Files touched:** ~/.melaya-runner/shared, ~/.melaya-runner/venv, ~/.melaya-runner/venv-version.txt, ~/.melaya-runner/cert-bundle-path, ~/.claude/.credentials.json, ~/.codex/auth.json, ~/.codex/models\_cache.json, ~/.melaya/luma/storage-state.json, ~/Documents/Melaya-Pipelines/\/outputs, /tmp/melaya-run-\/main.py - **Network endpoints:** wss://api.melaya.org, https://api.melaya.org/api/v1/runner/shared-bundle, https://api.anthropic.com/v1/models?limit=100, http://127.0.0.1:1234/v1/models, http://127.0.0.1:11434/api/tags, https://www.linkedin.com/login, https://luma.com/signin ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** dist/connection.js accepts authenticated Socket.IO runner:run/start\_crew\_strategy jobs and spawns server-provided Python in temp run dirs., dist/connection.js verifySignature only checks that a signature string is present, not a real HMAC/public-key verification., dist/sharedVendor.js fetches a remote shared Python bundle from /api/v1/runner/shared-bundle and writes it under ~/.melaya-runner., dist/pythonEnv.js creates ~/.melaya-runner/venv and installs many Python dependencies with pip at runtime., dist/detect.js reads ~/.claude/.credentials.json and ~/.codex/auth.json to detect local agent model availability. - **Evidence against:** package.json has no consumer install/postinstall/prepare hook; only prepublishOnly runs npm run build before publishing., CLI requires explicit melaya-runner invocation with --token before network connection or job handling., dist/sharedVendor.js verifies the bundle hash from the response and attempts path traversal sanitization before writing cache files., No code found writing MCP/Claude/Codex/Cursor configs, shell startup files, VCS hooks, or OS autostart entries., Claude/Codex token reads appear used for local model detection; inspected code sends model names, not raw tokens, to Melaya. ## Affected versions and remediation This report applies to @melaya/runner@1.0.76. - Review the evidence and your use of @melaya/runner@1.0.76 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.
