Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
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，该漏洞源于未设置PLATFORM_JWT_SECRET时JWT_SECRET被赋值为公开的dev-secret-change-me，且PLATFORM_ENV默认为dev导致生产防护未生效，远程未认证攻击者可伪造HS256令牌，通过被保护API路由的身份验证，可能导致权限提升。

Vulnerability Title
praisonai-platform: default JWT signing secret 'dev-secret-change-me' enables token forgery
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 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.
