  "details" : "### Summary\n\nCVE-2026-44338 (GHSA-6rmh-7xcm-cpxj) documents that PraisonAI ships a code-generator (`praisonai.deploy.api.generate_api_server_code`) that emits a Flask API server with authentication disabled by default. Users who follow the documented quickstart (`praisonai deploy --type api`) get a server that:\n\n- binds to `0.0.0.0` per the recommended sample YAML\n- exposes `/chat` and `/agents` endpoints\n- runs `praisonai.run()` on user-supplied JSON input — LLM orchestration with the API key materials present in the process environment\n- does not require any authentication\n\nThe PyPI wheel `praisonai==4.6.33` (current `@latest`) still ships the generator with `auth_enabled` defaulting to `False`. The fix shape is opt-in via `APIConfig(auth_enabled=True, auth_token=...)`.\n\n### Details\n\n**Anchor (file:line:symbol)**\n\n- Vulnerable artifact: `praisonai==4.6.33` on PyPI.\n- Defaults: `praisonai/deploy/models.py:29` — `auth_enabled: bool = Field(default=False, ...)`; `praisonai/deploy/models.py:30` — `auth_token: Optional[str] = Field(default=None, ...)`.\n- Generator: `praisonai/deploy/api.py:40` — `AUTH_ENABLED = {config.auth_enabled}`; `api.py:41` — `AUTH_TOKEN = {repr(config.auth_token)}`; `api.py:43-49` — `def check_auth(): if not AUTH_ENABLED: return True`.\n- CLI entry: documented as `praisonai deploy --type api` (vendor README); produces the generator output above with no flag required to suppress the warning, because no warning is emitted.\n\n**Vulnerable code (verbatim from installed wheel)**\n\n```python\n# praisonai/deploy/models.py (praisonai==4.6.33)\nclass APIConfig(BaseModel):\n    host: str = Field(default=\"127.0.0.1\", description=\"Server host\")\n    port: int = Field(default=8005, description=\"Server port\")\n    cors_enabled: bool = Field(default=True, description=\"Enable CORS\")\n    auth_enabled: bool = Field(default=False, description=\"Enable authentication\")     # line 29\n    auth_token: Optional[str] = Field(default=None, description=\"Authentication token\") # line 30\n```\n\n```python\n# praisonai/deploy/api.py (praisonai==4.6.33)\ncode = f\\'\\'\\'...\n# Authentication\nAUTH_ENABLED = {config.auth_enabled}      # False by default\nAUTH_TOKEN   = {repr(config.auth_token)}  # None by default\n\ndef check_auth():\n    if not AUTH_ENABLED:\n        return True                       # short-circuit, accept all\n    token = request.headers.get(\\'Authorization\\', \\'\\').replace(\\'Bearer \\', \\'\\')\n    return token == AUTH_TOKEN\n...\n\\'\\'\\'\n```\n\nA default invocation of the deploy command emits a server whose `check_auth()` short-circuits to `True` and accepts unauthenticated `/chat`, `/agents` POSTs.\n\n### PoC\n\n```python\n#!/usr/bin/env python3\n\"\"\"\nlegend-c420 PoC - PraisonAI 4.6.33 generates Flask API server with auth\ndisabled by default.

EXIT 0.` — vulnerable-default shape confirmed. `auth_enabled=False` by default, `check_auth()` short-circuits to `True`, fix toggle exists but is opt-in.\n\n### Impact\n\nAn operator who runs the vendor-documented quickstart (`pip install praisonai && praisonai deploy --type api`) gets a network-reachable Flask server that invokes `praisonai.run()` on attacker-supplied JSON with the user's LLM API keys in the process environment. The attacker reaches arbitrary LLM-orchestration (including any tool-use the agents define, which in PraisonAI commonly includes `python_repl`, `bash`, file I/O, and HTTP calls), with the host's API-key credit billed to the operator.\n\n- **Belief:** CVE-2026-44338 was filed and triaged.\n- **Reality:** `praisonai==4.6.33` is current `@latest` on PyPI (2026-05-16). The generator still defaults to `auth_enabled=False`.\n- **Gap:** The CVE acknowledges the fix shape exists. The fix is opt-in. The default-config consumer remains vulnerable.\n\n**Parent CVE:** CVE-2026-44338 / GHSA-6rmh-7xcm-cpxj",
