PraisonAI: PRAISONAI_CALL_AUTH=disabled environment variable unconditionally disables authentication

Summary

Setting PRAISONAI_CALL_AUTH=disabled completely disables all authentication on the /api/v1/agents/{id}/invoke endpoint. This bypass is advertised in the application's own error messages, making it likely to appear in production Docker and Compose configurations.

Details

# src/praisonai/praisonai/api/agent_invoke.py:32
_CALL_AUTH_DISABLED = os.getenv('PRAISONAI_CALL_AUTH', '').lower() == 'disabled'

async def verify_token(...) -> None:
    if _CALL_AUTH_DISABLED:
        return  # all authentication skipped unconditionally

The application's own error message advertises the bypass:

"Set CALL_SERVER_TOKEN or PRAISONAI_CALL_AUTH=disabled to run without authentication."

This causes the setting to appear in Docker/Compose configurations as a convenience option.

Proof of Concept

import os
os.environ["PRAISONAI_CALL_AUTH"] = "disabled"
# verify_token() now returns immediately for any request
# POST /api/v1/agents/any-agent/invoke → 200 OK (no token needed)

Common vulnerable deployment:

# docker-compose.yml
environment:
  - PRAISONAI_CALL_AUTH=disabled  # auth completely disabled

Impact

Full unauthenticated access to the agent invocation API. Any agent registered on the server can be triggered without credentials, potentially executing arbitrary actions depending on the agent's configured tools.
