Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 1.77.0 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The source exposes agent-invoked shell execution, a powerful dual-use capability that warrants a warning. The flagged credential handling is consistent with authentication to the Vercel AI Gateway and does not establish credential theft. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-17T06:15:37.385Z - **Finished:** 2026-10-17T06:24:08.749Z - **Download time:** 2033 ms - **Static scan time:** 21301 ms - **AI review time:** 488028 ms - **Total time:** 511364 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 agent builder provides a tool that can run caller-supplied shell commands. This is a powerful runtime capability, but inspection did not establish covert execution or another confirmed attack. - **Trigger:** An application or agent invokes the exposed execute-command tool. - **Impact:** Commands can affect the environment available to the application; the inspected path does not establish an unrequested command trigger. - **Evidence paths:** dist/dist-Cfv3ewR4.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-17T06:24:08.749Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The tool passes its supplied command to a child process and may return captured output. - **Rationale:** The source exposes agent-invoked shell execution, a powerful dual-use capability that warrants a warning. The flagged credential handling is consistent with authentication to the Vercel AI Gateway and does not establish credential theft. - **Files touched:** dist/dist-Cfv3ewR4.cjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The agent builder exposes an execute-command tool that accepts a command and working directory., The tool passes the supplied command to child\_process.exec and can return its output. - **Evidence against:** The flagged credential path uses the Vercel AI Gateway provider, with a configurable base URL and a gateway-specific token., The top-level package entrypoint throws and directs callers to specific subpaths. ## Affected versions and remediation This report applies to @mastra/server@1.77.0. - Review the evidence and your use of @mastra/server@1.77.0 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.
