📝 WalkthroughWalkthroughThis PR hardens auth token consistency, sandbox workload lifecycle, and API key confidentiality across the gateway, cloud deployment, and sandbox execution paths. Auth token is now always exported to the environment at gateway init; deployment no longer exposes API keys in gcloud argv; and sandbox timeouts now reliably clean up remote files and force-stop running workloads.

GCP provider still exposes secrets via gcloud run deploy --set-env-vars argv
src/praisonai/praisonai/deploy/providers/gcp.py’s GCPProvider.deploy() constructs env_str from self.config.env_vars and passes it as --set-env-vars <k=v,...>; if env_vars contains API keys/secrets, they will end up in the gcloud command line (process tables/command logs). This remains unaddressed compared to the src/praisonai/praisonai/deploy.py fix that switches to --env-vars-file.
- Update the GCP provider deploy path to use a secure temp env-var file +
--env-vars-file(mode0600) instead of--set-env-vars.

Container naming logic is correct, but the same fix is missing from execute().
The deterministic container naming and --name flag correctly address the orphan container issue for run_command(). However, the execute() method (lines 145-151) uses _build_docker_command() which does not add --name, and its timeout handler (lines 180-191) only calls proc.kill() without docker kill. This leaves execute() vulnerable to the same orphan container problem this PR aims to fix.
Consider applying the same pattern to execute() by:
- Adding container naming to
_build_docker_command() - Adding
docker killto the timeout handler inexecute()

Greptile SummaryThis PR fixes three security issues in the gateway/sandbox/deploy layer: unifying the auth token source of truth, preventing resource leaks on sandbox timeout, and avoiding API key exposure in process arguments.
Confidence Score: 4/5Safe to merge; all three stated fixes are implemented correctly and the Docker/deploy changes are straightforward improvements with no regressions. The gateway token write-back changes process-global state in init, which works correctly for the intended single-instance deployment but could silently overwrite a concurrent instance's token in the same process. The SSH _run_command_with_limits now double-wraps the timeout for the execute_code path (harmless, but the redundancy suggests the _build_command timeout injection could be removed now). Neither issue affects correctness in normal deployment. ssh.py — the interaction between _build_command's timeout injection and the new _run_command_with_limits wrapper is worth a second look to decide whether one of the two wrappings should be removed.

execute_code path
_run_command_with_limits now wraps the incoming command with timeout {N} sh -c '...', but for the execute_code caller the command string was already built by _build_command, which injects timeout {N} directly. The final remote command becomes cd /wd && timeout 30 sh -c 'ulimit -v … && timeout 30 python /file.py' — two nested timeout calls for the same duration. The fix is effective and needed for the execute_file path (which skips _build_command), but the inner timeout from _build_command is now redundant for execute_code.
| if self.config.auth_token: | ||
| os.environ["GATEWAY_AUTH_TOKEN"] = self.config.auth_token |
There was a problem hiding this comment.
os.environ["GATEWAY_AUTH_TOKEN"] is now set during __init__, meaning every subprocess spawned from this point forward inherits the token. In a typical single-gateway deployment this is the intended single-source-of-truth effect, but in multi-tenant or test-runner scenarios where multiple WebSocketGateway instances are constructed in the same process, a later instance's token will silently overwrite an earlier one's in the global env, potentially causing auth mismatches for already-running request handlers that re-read the env var.
Fixes #1743
Summary
This PR addresses three critical security vulnerabilities identified in the PraisonAI wrapper layer:
Fix 1: Gateway Magic-Link Auth Secret Mismatch
Problem: HTTP/magic-link verification and WebSocket verification used different secret sources, breaking default login flow and creating auth inconsistencies.
Solution: Export resolved token to environment to ensure single source of truth across all auth paths.
Fix 2: Sandbox Timeout Resource Leaks
Problem:
Solution:
Fix 3: Cloud Deploy API Key Exposure
Problem: OPENAI_API_KEY exposed in gcloud argv (visible in process table/CI logs).
Solution: Replace inline argv secrets with secure temporary YAML file approach.
