- Add ManagedSandboxRequired exception for package installation safety - Modify LocalManagedAgent to use compute providers for secure execution - Implement compute-based tool execution routing for shell commands - Add host_packages_ok safety opt-out flag for developer workflows - Remove unused sandbox_type config field - Add comprehensive tests for security functionality Security improvements: - Packages install in sandbox when compute provider attached - Raise exception when packages specified without compute/opt-out - Route execute_command, read_file, write_file, list_files through compute - Maintain backward compatibility with explicit opt-out flag 🤖 Generated with [Claude Code](https://claude.ai/code) Co-authored-by: Mervin Praison <MervinPraison@users.noreply.github.com>

Caution Review failedAn error occurred during the review process. Please try again later. 📝 WalkthroughWalkthroughThis PR implements security controls to prevent unintended host-level package installation and tool execution in LocalManagedAgent. It introduces compute-bridged tool execution, validates compute provider attachment for packages, adds a ManagedSandboxRequired exception, and replaces sandbox_type configuration with host_packages_ok flag.

Greptile SummaryThis PR addresses sandbox security issue #1426 by routing shell/file tool execution through a compute provider (Docker, E2B, Modal, etc.) when one is attached, and blocking host-level Key changes:
Confidence Score: 3/5Safe to merge once the three stale test assertions are corrected; the security logic itself is sound. The prior security injection issues (unescaped src/praisonai-agents/tests/managed/test_managed_factory.py — three assertions at lines 679, 703, and 726 need to be updated to match the Important Files Changed

@claude You are the FINAL architecture reviewer. If the branch is under MervinPraison/PraisonAI (not a fork), you are able to make modifications to this branch and push directly.

What Was Fixed:
🔒 Security Assessment: SAFE TO MERGEThe PR successfully implements sandbox security for managed agents. With the applied fixes, the code now properly isolates package installation and tool execution within compute environments while providing safe fallback options for development workflows. Recommendation: ✅ MERGE - All blocking security issues resolved. |
- Add shlex.quote() to all file paths and directory arguments - Use printf instead of echo to preserve file content integrity - Quote package names in pip install commands - Convert silent pip failures to structured RuntimeError exceptions - Add -- separators to prevent option injection Addresses command injection vulnerabilities identified by security review.

There was a problem hiding this comment.
test_compute_read_file_bridge will fail
The assertion at line 679 expects the raw, unquoted path, but the implementation in managed_local.py was updated (in commit b91ab6c5) to use shlex.quote() and add the -- end-of-options separator:
# managed_local.py line 342 (actual)
f"cat -- {shlex.quote(file_path)}"
# produces: "cat -- '/path/to/file.txt'"The test therefore expects a command that is never generated:
# Expected (test line 679)
mock_compute.execute.assert_called_once_with(
"test_instance", "cat /path/to/file.txt", timeout=60
)
# Actual call
"cat -- '/path/to/file.txt'"This test will fail at CI time. Fix:
| mock_compute.execute.assert_called_once_with("test_instance", "cat /path/to/file.txt", timeout=60) | |
| mock_compute.execute.assert_called_once_with("test_instance", "cat -- '/path/to/file.txt'", timeout=60) |
