Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.1.3 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source implements the documented, explicitly invoked sandbox deployer behavior and has no install-time execution. Network, environment, shell, and token handling are caller-configured features with no covert malicious chain found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-02T15:31:53.485Z - **Finished:** 2026-08-02T15:32:25.982Z - **Download time:** 510 ms - **Static scan time:** 1471 ms - **AI review time:** 30515 ms - **Total time:** 32497 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:** No confirmed malicious attack surface. The package intentionally deploys caller-selected build output to a caller-provided sandbox when its deployment APIs are invoked. - **Trigger:** Explicit SandboxDeployer/deployToSandbox or client-helper invocation - **Impact:** Can run the caller's build and install command in that caller-configured remote sandbox. - **Evidence paths:** package.json, dist/index.js, dist/shared-C-piQAcU.js, dist/client/index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-02T15:32:25.982Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** sandbox deployment, optional Edge Config update, and server-side proxying - **Rationale:** Source implements the documented, explicitly invoked sandbox deployer behavior and has no install-time execution. Network, environment, shell, and token handling are caller-configured features with no covert malicious chain found. - **Files touched:** .env, .env.production, .env.local, sandbox-deployment.json, {remoteDir}/.deploy.tgz, {remoteDir}/.mastra-server.sh, {remoteDir}/.mastra-server.pid, {remoteDir}/.mastra-server.log - **Network endpoints:** https://api.vercel.com/v1/edge-config/{edgeConfigId}/items ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** dist/index.js deploys supplied build output and runs an explicit install command inside the supplied sandbox., dist/index.js optionally sends a caller-provided Vercel token to Edge Config., dist/client/index.js proxies requests only when its exported helpers are invoked. - **Evidence against:** package.json has no install lifecycle hooks or bin entrypoint., Entrypoints only define exports; no deployment, network call, or credential access occurs on import., dist/index.js uses caller-provided sandbox, directory, environment, and alias options., dist/shared-C-piQAcU.js shell commands are confined to the caller-supplied sandbox deployment workflow., No source evidence of local credential harvesting, covert exfiltration, payload download, or agent-control mutation. ## Affected versions and remediation This report applies to @mastra/deployer-sandbox@0.1.3. - Review the evidence and your use of @mastra/deployer-sandbox@0.1.3 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.
