PraisonAI is a multi-agent teams system. Prior to 0.1.6, praisonai_platform/services/auth_service.py falls back to the public dev-secret-change-me HS256 signing key when PLATFORM_JWT_SECRET is unset, while the startup and token-issuance guards are disabled because PLATFORM_ENV also defaults to dev. An unauthenticated attacker can sign a JWT containing an attacker-chosen sub value, and AuthService._verify_token() accepts it as an authenticated identity, enabling user or workspace-owner impersonation when a target identifier is known. This vulnerability is fixed in praisonai-platform 0.1.6.

Affected: PyPI: praisonai-platform

- Affected: praisonai-platform (PyPI) <= 0.1.4 — including 0.1.4, the version GHSA-3qg8-5g3r-79v5 declares as the patch; main HEAD 8acf77c531e624c46d3d61dcae37e9942e90972c is also affected. File src/praisonai-platform/praisonai_platform/services/auth_service.py

- CWE: CWE-1188 (Insecure Default Initialization) + CWE-798 (Use of Hard-coded Credentials) -> CWE-287 (Improper Authentication)

## Overview

GHSA-3qg8-5g3r-79v5 (Critical) reported that praisonai-platform's JWT signing secret defaulted to the hardcoded literal "dev-secret-change-me", and that the production guard meant to prevent this was default-open (it only fired when PLATFORM_ENV != "dev", but PLATFORM_ENV defaults to "dev"). That advisory declares the issue patched in >= 0.1.4. **It is not.** The shipped praisonai-platform==0.1.4 (and current main) still resolves the signing key to "dev-secret-change-me" in any deployment that does not explicitly set PLATFORM_JWT_SECRET, because the 0.1.4 change merely duplicated the same default-open guard into a second function instead of failing closed. An unauthenticated attacker reads the literal from the public source, forges a JWT with an arbitrary sub, and is authenticated as that user — including a workspace owner.

## Impact

Any deployment that runs praisonai-platform 0.1.4 without explicitly exporting a strong PLATFORM_JWT_SECRET signs and verifies session JWTs with the publicly known key "dev-secret-change-me". The package's documented entry point — `python -m pra…
