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 flagged gateway and process-execution code resolve to package-aligned AI provider and project-agent functionality, with command availability gated by workspace configuration and an enabled tool flag. The manifest has no install lifecycle hook, and inspection found no confirmed malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-17T05:48:30.513Z - **Finished:** 2026-10-17T05:54:35.770Z - **Download time:** 1030 ms - **Static scan time:** 23689 ms - **AI review time:** 340538 ms - **Total time:** 365257 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 reviewed network and command execution paths align with provider requests and enabled project agent functionality. - **Trigger:** Provider token counting or an enabled project agent invoking its command tool. - **Impact:** No unauthorized credential transfer, persistence, or other attack effect was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T05:54:35.770Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Gateway authentication uses a dedicated gateway token; other token counting helpers send provider keys to provider APIs. The shell tool runs the requested project command when enabled. - **Rationale:** The flagged gateway and process-execution code resolve to package-aligned AI provider and project-agent functionality, with command availability gated by workspace configuration and an enabled tool flag. The manifest has no install lifecycle hook, and inspection found no confirmed malicious behavior. - **Files touched:** package.json, dist/index.js, dist/dist-L0EogwX\_.js, dist/dist-Xj9TvH1A.cjs, dist/server/handlers/agents.js, dist/server/handlers/agents.cjs - **Network endpoints:** https://ai-gateway.vercel.sh/v1/ai, https://api.openai.com/v1/responses/input\_tokens, https://api.anthropic.com/v1/messages/count\_tokens ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json lists build, generation, check, and test scripts without an install lifecycle hook; the top-level entrypoint throws and directs users to subpath imports., The flagged bundle’s gateway code uses a dedicated gateway token and targets the Vercel AI gateway; provider token-counting helpers send provider keys to their corresponding provider APIs., Command execution is part of the project agent tool and is exposed only when a workspace sandbox enables it and the corresponding tool flag is enabled., The other required bundle paths contain server route handlers, schemas, and runtime utilities consistent with the package’s declared server entrypoints; no independent malicious transfer or persistence behavior was established. - **Evidence against:** The source includes outbound provider requests and shell execution, but they occur in provider-specific helpers and an enabled project agent tool. ## Affected versions and remediation This report applies to @mastra/server@1.62.0. - Review the evidence and your use of @mastra/server@1.62.0 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.
