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. The inspected network behavior belongs to configurable logging transports, and the main logger uses configured transports. The manifest shows no install lifecycle hook, and the inspected dependencies serve as logging and formatting components. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-21T12:07:49.953Z - **Finished:** 2026-10-21T12:08:48.631Z - **Download time:** 510 ms - **Static scan time:** 117 ms - **AI review time:** 58050 ms - **Total time:** 58678 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. The package provides logging transports that send logs to destinations configured by the application. - **Trigger:** An application creates and uses a logger with a configured transport. - **Impact:** Log records are delivered to the destination selected by the application; no package-selected recipient or unrelated attack behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-21T12:08:48.631Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The HTTP and Upstash transports send buffered log records to their configured destinations; the main logger wires configured transports into Pino. - **Rationale:** The inspected network behavior belongs to configurable logging transports, and the main logger uses configured transports. The manifest shows no install lifecycle hook, and the inspected dependencies serve as logging and formatting components. ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes separate logger entrypoints and declares pino and pino-pretty as runtime dependencies., The package lifecycle scripts shown in the manifest are build, watch, test, and lint commands; no install hook is declared., The main logger passes caller options and configured transports to Pino., The HTTP transport sends buffered logs to its configured URL, with caller-provided method and headers., The Upstash transport sends buffered logs to its configured URL using its supplied token., The inspected dependency entrypoints identify pino as a logger and pino-pretty as a log formatter. ## Affected versions and remediation This report applies to @mastra/loggers@1.3.9. - Review the evidence and your use of @mastra/loggers@1.3.9 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.
