PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have an insecure default cryptographic key. The JWT signing secret defaults to the hardcoded literal `"dev-secret-change-me"` when `PLATFORM_JWT_SECRET` is unset. A safety check exists but only fires when `PLATFORM_ENV != "dev"`; the default value of `PLATFORM_ENV` is `"dev"`, so the check is silently bypassed in any deployment that does not explicitly opt out. The attacker reads the literal from this public source file, mints a JWT with arbitrary `sub` and `email` claims, and authenticates as any existing user (including workspace owners and admins). PraisonAI Platform version 0.1.4 patches the issue.

## Summary

**Type:** Insecure default cryptographic key. The JWT signing secret defaults to the hardcoded literal `"dev-secret-change-me"` when `PLATFORM_JWT_SECRET` is unset. A safety check exists but only fires when `PLATFORM_ENV != "dev"`; the default value of `PLATFORM_ENV` is `"dev"`, so the check is silently bypassed in any deployment that does not explicitly opt out. The attacker reads the literal from this public source file, mints a JWT with arbitrary `sub` and `email` claims, and authenticates as any existing user (including workspace owners and admins). **File:** `src/praisonai-platform/praisonai_platform/services/auth_service.py`, lines 25-36 and 114-137. **Root cause:** the production-mode guard checks `os.environ.get("PLATFORM_ENV", "dev") != "dev"` — but the default is `"dev"`, so a clean deployment that just imports the package and runs `uvicorn praisonai_platform.api.app:app` proceeds with the hardcoded secret. The package documentation does not warn loudly enough that BOTH variables must be set; the guard suppresses itself when either condition is missed. JWT verification at line 129 trusts whatever the token says (`sub`, `email`, `name`) once the HMAC-SHA256 signature validates against the publicly-known secret. Since the verifier accepts forged tokens for any user_id, the attacker becomes that user across every authenticated route.
