Docker container sandbox provider for Mastra workspaces

AI Security Review

scanned 2d ago · by lpm-firewall-ai

The package has no install lifecycle hook, and its inspected entrypoint and prepared dependencies align with Docker sandbox functionality. The flagged environment and runtime references do not establish an attack surface.

Static reason

No blocking static signals were detected.

Trigger

Importing the library exposes its sandbox APIs; secret handling occurs when a caller invokes the secret build method.

Impact

No malicious or unauthorized effect was identified.

Mechanism

The inspected gRPC code traces resolved addresses and parses service configuration. Secret names are supplied through method options and validated before use.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 94.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest points to the Docker sandbox entrypoint and lists Docker, gRPC, and tar-stream dependencies; its scripts contain build and test commands, with no install lifecycle hook.
The flagged gRPC runtime code traces resolved addresses and parses gRPC service configuration records.
The prepared gRPC dependency identifies itself as a gRPC library and its entrypoint exports gRPC APIs.
The prepared dockerode manifest describes a Docker Remote API module.
The prepared tar-stream entrypoint exports archive extraction and packing functions.
The exported secret build method accepts explicit options and validates the supplied secret names.
