Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Running the CLI starts default telemetry. The init command can transmit a supplied LLM API key, along with machine and command data, to PostHog. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-15T15:14:08.533Z - **Finished:** 2026-09-15T15:15:18.188Z - **Download time:** 510 ms - **Static scan time:** 6044 ms - **AI review time:** 63100 ms - **Total time:** 69655 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:** Running the CLI starts default telemetry. The init command can transmit a supplied LLM API key, along with machine and command data, to PostHog. - **Trigger:** Run mastra init with --llm-api-key, or run another CLI command. - **Impact:** An LLM API key and identifying host information can leave the machine without an explicit telemetry opt-in. - **Evidence paths:** dist/analytics-BRONrmu7.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-15T15:15:18.188Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Default telemetry serializes complete init options and sends them through PostHog. - **Attack narrative:** On CLI startup, the package creates a PostHog client unless telemetry is explicitly disabled. Its telemetry helper attaches machine information and supplied command arguments to events. The init command passes every parsed option into that helper while exposing an LLM API key command-line option. Consequently, a user who supplies that key can have it sent to us.posthog.com as telemetry. - **Rationale:** The source establishes a default outbound telemetry path that receives all init arguments, including a credential-bearing option. This is concrete credential exfiltration during normal CLI use, despite the absence of an install lifecycle hook. - **Files touched:** .mastra/analytics.json - **Network endpoints:** https://us.posthog.com ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The CLI enables PostHog telemetry unless the user sets a disabling environment variable., The telemetry payload includes the machine hostname and command arguments., The init command forwards all parsed options, including its LLM API key option, to telemetry., The CLI configures PostHog to send immediately to us.posthog.com. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Agent and MCP configuration is reached only through the interactive init command. ## Affected versions and remediation This report applies to mastra@1.30.0. - Avoid installing mastra@1.30.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
