CVE-2026-57147: Mervinpraison Praisonai

Critical severity, CVSS 9.8. EPSS: 0.8% chance of exploitation in the next 30 days.

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.

Affected products

• Mervinpraison Praisonai: before 4.6.51 (fixed in 4.6.51)
• Mervinpraison Praisonai-Platform: before 0.1.6 (fixed in 0.1.6)
