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. The proxy forwards an existing platform token to an unrestricted configurable endpoint, creating conditional credential exposure. Other flagged process calls are tied to deploy lockfile generation and supplied-file validation, and the manifest shows no install lifecycle hook. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-17T06:32:55.061Z - **Finished:** 2026-10-17T06:34:23.788Z - **Download time:** 510 ms - **Static scan time:** 2365 ms - **AI review time:** 85851 ms - **Total time:** 88727 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:** The Agent Learning proxy can send a platform bearer token to an endpoint configured through an environment variable. The source does not restrict that endpoint to the default Mastra host. - **Trigger:** A request reaches the proxy on a loopback host while the platform token and project ID are set; an operator may also configure a different endpoint. - **Impact:** If configured with an unintended recipient, the proxy discloses the platform token to that recipient; the source does not establish that this occurs by default. - **Evidence paths:** dist/server/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-17T06:34:23.788Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The proxy builds the upstream URL from the configured endpoint and sends the platform token in its Authorization header without checking the destination host. - **Rationale:** The proxy forwards an existing platform token to an unrestricted configurable endpoint, creating conditional credential exposure. Other flagged process calls are tied to deploy lockfile generation and supplied-file validation, and the manifest shows no install lifecycle hook. - **Files touched:** dist/server/index.js - **Network endpoints:** https://output.signals.mastra.ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package scripts contain build, test, and lint tasks, with no install lifecycle hook shown., The proxy uses a Mastra endpoint by default and accepts requests only from loopback hosts with matching origins., The proxy requires a platform token and project ID, then builds the upstream URL from an environment-configured endpoint without restricting its host., The upstream GET includes the platform token as a bearer credential., The flagged package manager call is in a deploy output lockfile-generation method and uses the lockfile-only option., The validator child process imports the supplied file as part of validation; the ESM and CommonJS builds show this flow. - **Evidence against:** The token transfer is part of an Agent Learning proxy, and its default destination is a Mastra host., The proxy is limited to loopback requests and rejects cross-origin requests., The package has no install lifecycle hook in its scripts., The other reviewed process execution is associated with lockfile generation or validation of a supplied file. ## Affected versions and remediation This report applies to @mastra/deployer@1.63.0. - Review the evidence and your use of @mastra/deployer@1.63.0 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.
