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 optional Studio UI starts PostHog telemetry automatically with autocapture enabled, which is a real but warning-level privacy risk. The reviewed code provides a browser-level opt-out and does not show credentials or application records flowing to the analytics host. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-30T23:26:14.849Z - **Finished:** 2026-10-30T23:27:06.076Z - **Download time:** 764 ms - **Static scan time:** 7844 ms - **AI review time:** 42618 ms - **Total time:** 51227 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:** Undisclosed browser analytics in the optional Studio UI; no credential exfiltration identified. - **Trigger:** A deployed Studio UI is loaded and its analytics component mounts. - **Impact:** PostHog may receive automatically captured UI interaction data. The inspected code does not show service credentials or application records being sent. - **Evidence paths:** dist/studio/assets/main-DW8Ek0u0.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-30T23:27:06.076Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The UI initializes PostHog with autocapture enabled and sends analytics to https://us.posthog.com. The browser setting MASTRA\_TELEMETRY\_DISABLED can turn it off. - **Rationale:** The optional Studio UI starts PostHog telemetry automatically with autocapture enabled, which is a real but warning-level privacy risk. The reviewed code provides a browser-level opt-out and does not show credentials or application records flowing to the analytics host. - **Network endpoints:** https://us.posthog.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** When the Studio UI mounts, it initializes PostHog at https://us.posthog.com and registers mastraSource: playground., The bundled PostHog configuration enables autocapture by default., The package lets users disable Studio telemetry with the MASTRA\_TELEMETRY\_DISABLED browser setting. - **Evidence against:** Studio is disabled by default and must be explicitly enabled in the deployer configuration., The package entry point reads service-token environment variables to configure authentication; no evidence shows those tokens being sent to PostHog., No install, preinstall, or postinstall scripts are declared. ## Affected versions and remediation This report applies to @mastra/deployer-cloud@1.81.0. - Review the evidence and your use of @mastra/deployer-cloud@1.81.0 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.
