Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 14 low-signal pattern(s) reviewed. - **Verdict:** Manual Review - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Under Review - **Threat category:** Unknown - **Selected version:** 1.76.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected source supports normal AI Gateway authentication and does not verify the scanner's credential redirect and persistence claim. The full flagged bundle behavior and required clean citation coverage remain unresolved, so this review needs manual review. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 57.0% - **Started:** 2026-10-17T06:07:39.164Z - **Finished:** 2026-10-17T06:15:12.049Z - **Download time:** 1527 ms - **Static scan time:** 21121 ms - **AI review time:** 430236 ms - **Total time:** 452885 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 established in the inspected excerpts. The flagged provider code sends gateway credentials to its configured AI Gateway endpoint, but the broader bundle behavior remains unresolved. - **Trigger:** Using the bundled AI Gateway provider. - **Impact:** The inspected behavior supports ordinary gateway authentication; the scanner's credential redirect and persistence claim was not verified. - **Evidence paths:** dist/dist-C68HDUAO.js - **Review source:** ai\_review - **Reviewed:** 2026-10-17T06:15:12.049Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The provider obtains a gateway token from its option or environment setting and uses it in an authorization header. - **Rationale:** The inspected source supports normal AI Gateway authentication and does not verify the scanner's credential redirect and persistence claim. The full flagged bundle behavior and required clean citation coverage remain unresolved, so this review needs manual review. - **Files touched:** dist/dist-C68HDUAO.js - **Network endpoints:** https://ai-gateway.vercel.sh/v1/ai ### Review decision - **Verdict:** Manual Review - **Confidence:** 57.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest routes package entrypoints through dist files and lists no lifecycle hooks in its scripts., The bundle contains an AI Gateway provider that sends its gateway token to the Vercel AI Gateway endpoint., That provider reads AI\_GATEWAY\_API\_KEY or a caller-supplied option as its token., The top-level entrypoint throws and directs users to specific subpath imports. - **Evidence against:** The inspected provider code does not show an Anthropic credential being redirected or persisted. ## Affected versions and remediation This report applies to @mastra/server@1.76.0. - Review the evidence and your use of @mastra/server@1.76.0 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.
