CVE-2026-57148: Mervinpraison Praisonai

Critical severity, CVSS 9.8. EPSS: 0.6% 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 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 products

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