@mastra/deployer@1.62.0
AI Security Review
scanned 6d ago · by lpm-firewall-aiThe source shows a real but constrained credential-forwarding risk when an operator overrides the proxy endpoint. The development and loopback gates reduce exposure, while the endpoint override remains unrestricted; this supports a warning rather than a block.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A request reaches the Agent Learning proxy while development mode and Studio are enabled, with the required platform token and project ID set.
Impact
If configured with an unrelated endpoint, the proxy can disclose the platform token to that recipient.
Mechanism
The handler resolves the request path against the configured endpoint and places the platform token in the upstream Authorization header.
AI rationale
The source shows a real but constrained credential-forwarding risk when an operator overrides the proxy endpoint. The development and loopback gates reduce exposure, while the endpoint override remains unrestricted; this supports a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package manifest defines no install or other lifecycle hook.
- The development proxy requires platform token and project ID environment variables, and accepts a configurable upstream endpoint.
- The proxy sends the platform token as a bearer credential to the resolved upstream URL.
- The proxy is mounted only when both development mode and Studio are enabled, and it rejects non-loopback requests.
Evidence against
- The proxy defaults to Mastra’s platform endpoint and has development-only, loopback, and same-origin request checks.
