Detailsinfo

A vulnerability, which was classified as critical, was found in MervinPraison PraisonAI and praisonai-platform up to 0.1.5. This affects the function AuthService._verify_token of the file praisonai_platform/services/auth_service.py of the component AuthService. The manipulation with an unknown input leads to a improper authentication vulnerability. CWE is classifying the issue as CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

It is possible to read the advisory at github.com. This vulnerability is uniquely identified as CVE-2026-57147 since 06/24/2026. The exploitability is told to be easy.
