CVE-2026-61433.

Disclosure summary

# API deploy code generator embeds unescaped YAML fields into Python source ## Summary PraisonAI's API deployment generator copies `deploy.api.host` from `agents.yaml` directly into generated Python source without safe literal encoding. A malicious PraisonAI project can set that host value to a Python expression splice; when an operator runs the API deploy flow, the generated server source compiles and executes the injected expression at startup. The same generator also embeds `agents_file` directly into generated route-handler expressions, giving a second route-time source injection site if the agent file path is attacker-controlled. ## Technical Details The vulnerable path starts with deployment configuration parsing. `Deploy.from_yaml()` reads the operator-supplied `agents.yaml`, `validate_agents_yaml()` accepts `deploy.api.host` as a string, and API deployments call `start_api_server(self.agents_file, self.config.api)`. `start_api_server()` calls `generate_api_server_code()` and executes the generated Python file with `python`. The current generator in `src/praisonai/praisonai/deploy/api.py` treats deployment data as Python syntax: ```python def generate_api_server_code(agents_
