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 inspection found no install hook or confirmed attack behavior. The scanner’s flagged configuration paths are inert expressions, while the observed telemetry and credential requests align with CLI analytics and Mastra platform authentication. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-11T17:20:11.250Z - **Finished:** 2026-10-11T17:21:15.760Z - **Download time:** 767 ms - **Static scan time:** 2066 ms - **AI review time:** 61677 ms - **Total time:** 64510 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 attack was identified in the inspected source. The package provides a CLI, uses limited command telemetry, and handles Mastra platform credentials through platform authentication. - **Trigger:** The CLI runs when invoked; platform authentication occurs when a platform feature requests a token. - **Impact:** No malicious effect was established from these behaviors. - **Review source:** ai\_review - **Reviewed:** 2026-10-11T17:21:15.760Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Telemetry sends selected command options to PostHog. Platform code verifies credentials with the Mastra platform; the flagged editor configuration paths are not used by a write operation. - **Rationale:** Source inspection found no install hook or confirmed attack behavior. The scanner’s flagged configuration paths are inert expressions, while the observed telemetry and credential requests align with CLI analytics and Mastra platform authentication. - **Network endpoints:** us.posthog.com ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes a CLI entrypoint and has no install lifecycle hook., The flagged editor configuration paths are standalone path expressions; no write operation uses them., Telemetry receives a restricted set of command options, and the CLI sends it to PostHog., Mastra credentials are sent to the Mastra platform for token verification during platform authentication. ## Affected versions and remediation This report applies to create-mastra@1.34.0. - Review the evidence and your use of create-mastra@1.34.0 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.
