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. Source establishes conditional forwarding of an existing service token to a configurable destination without an allowlist. This warrants a warning for dangerous credential exposure, while the inspected behavior does not establish malware intent or justify publication blocking. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-01T19:00:34.449Z - **Finished:** 2026-10-01T19:02:15.019Z - **Download time:** 1274 ms - **Static scan time:** 1453 ms - **AI review time:** 97841 ms - **Total time:** 100570 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:** Configured gateway routing can expose an existing Anthropic OAuth token to an unrestricted operator-selected destination. This is conditional credential exposure; no confirmed malicious attack was established. - **Trigger:** Run an Anthropic OAuth model through gateway routing with a gateway API key and a configured gateway URL. - **Impact:** The selected gateway receives a service session credential rather than only credentials supplied for that gateway. - **Evidence paths:** dist/index.js, dist/agents/model.js, dist/agents/mastracode-gateway.js, dist/providers/claude-max.js, dist/auth/storage.js - **Review source:** ai\_review - **Reviewed:** 2026-10-01T19:02:15.019Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The gateway supplies its configured URL to an OAuth fetch wrapper that attaches the stored Anthropic bearer token without restricting the destination. - **Rationale:** Source establishes conditional forwarding of an existing service token to a configurable destination without an allowlist. This warrants a warning for dangerous credential exposure, while the inspected behavior does not establish malware intent or justify publication blocking. - **Files touched:** auth.json - **Network endpoints:** https://gateway-api.mastra.ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The agent entrypoint activates dynamic model resolution., Model resolution accepts a gateway URL from settings or MASTRA\_GATEWAY\_URL without a destination allowlist., Gateway forwarding activates when a gateway model is selected and a gateway API key exists., The Anthropic OAuth branch connects stored credentials to the configured gateway., The OAuth fetch wrapper obtains the Anthropic token, adds a bearer header, and sends it to the supplied URL., AuthStorage loads existing credentials from auth.json. - **Evidence against:** No npm install lifecycle hooks or runtime self-dependency were found., Credential forwarding requires gateway model selection and a gateway API key; no covert default recipient was established. ## Affected versions and remediation This report applies to @mastra/code-sdk@1.10.1. - Review the evidence and your use of @mastra/code-sdk@1.10.1 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.
