Security Notes
Critical security risks identified: 1. **Lack of Package Integrity Verification**: Downloaded packages (Hatch, Python, Docker) are NOT cryptographically verified (no checksums, no signatures). This is explicitly stated in 'Limits and Known Issues' and means malicious packages or compromised registries/networks could lead to arbitrary code execution without detection. 2. **System-Level Code Execution with Elevated Privileges**: The 'System Installer' executes system package manager commands (e.g., `apt`) which can require `sudo`. Combined with the lack of package integrity verification, this presents a severe risk of system compromise if untrusted packages specify malicious system dependencies. 3. **Default Auto-Approval in Non-TTY Environments**: The dependency installation orchestrator automatically approves installation prompts in non-TTY environments. While useful for CI/CD, this automates the execution of unverified code, exacerbating the risk. 4. **Race Conditions for Critical State Files**: 'Limits and Known Issues' notes non-atomic file I/O for `environments.json` and package caches, leading to potential corruption. This can have security implications if state is manipulable. 5. **Supply Chain Risk**: Direct Git URL dependencies for `hatch_validator` and `@artessan-devs/sr-uv-plugin` in `pyproject.toml` introduce additional risk if those repositories are compromised. The project's own documentation clearly states it is 'less suitable for: Production deployments, Multi-tenant systems, High-security environments'.
