Affected: MervinPraison PraisonAI, MervinPraison praisonai-platform

PraisonAI is a multi-agent teams system. Prior to 0.1.6, praisonai_platform/services/auth_service.py assigns the public dev-secret-change-me value to JWT_SECRET when PLATFORM_JWT_SECRET is unset, and its production guard does not run when PLATFORM_ENV is also unset because that setting defaults to dev. A remote unauthenticated attacker can mint an HS256 token with an arbitrary sub and email, and the platform's AuthService._verify_token() and get_current_user dependency accept the forged identity for protected API routes. This vulnerability is fixed in praisonai-platform 0.1.6.

## TL;DR

`praisonai_platform/services/auth_service.py` lines 25-37:

```python _DEFAULT_SECRET = "dev-secret-change-me" JWT_SECRET = os.environ.get("PLATFORM_JWT_SECRET", _DEFAULT_SECRET) JWT_ALGORITHM = "HS256" JWT_TTL_SECONDS = int(os.environ.get("PLATFORM_JWT_TTL", str(30 * 24 * 3600)))

if JWT_SECRET == _DEFAULT_SECRET and os.environ.get("PLATFORM_ENV", "dev") != "dev": raise RuntimeError( "PLATFORM_JWT_SECRET must be set to a strong random value in production. " "Set PLATFORM_ENV=dev to suppress this check during development." ) ```

The guard at line 33 is meant to catch the "deployed to production with the default secret" failure mode. But it only fires when **both**:

- the operator left `PLATFORM_JWT_SECRET` unset (so `JWT_SECRET` is the default literal), **and** - the operator explicitly set `PLATFORM_ENV` to something other than `"dev"`.

If the operator…
