CVE-2026-55533: Mervinpraison Praisonai

High severity, CVSS 8.2. EPSS: 0.5% chance of exploitation in the next 30 days.

PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.58, create_auth_middleware() allows requests when auth=api-key lacks PRAISONAI_API_KEY or JWT authentication lacks PRAISONAI_JWT_SECRET. An externally bound Recipe server can therefore accept unauthenticated POST /v1/recipes/run requests despite authentication being enabled. This issue is fixed in version 4.6.58.

Affected products

• Mervinpraison Praisonai: before 4.6.58 (fixed in 4.6.58)
