Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Mervin Praison PraisonAI是Mervin Praison个人开发者开源的一个低代码多智能体协作框架。 Mervin Praison PraisonAI 4.6.51之前版本存在安全漏洞，该漏洞源于praisonai_platform/services/auth_service.py在未设置PLATFORM_JWT_SECRET时回退到公开的dev-secret-change-me HS256签名密钥，同时因PLATFORM_ENV默认为dev导致启动和令牌签发保护被禁用，未经身份验证

Vulnerability Title
praisonai-platform 0.1.4 still boots on the hardcoded JWT secret dev-secret-change-me (default-open production guard)
Source: CVE Program / CVE List V5
Vulnerability Description
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.
