CVE-2026-55528: 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 praisonaiagents 1.6.58, AgentServer exposes ServerConfig.auth_token but AgentServer._create_app does not check it on any route. A remote caller can subscribe, publish, and perform other actions without a valid bearer token or X-Auth-Token even when authentication is configured. This issue is fixed in version 1.6.58.

Affected products

• Mervinpraison Praisonai: before 4.6.58 (fixed in 4.6.58)
• Mervinpraison Praisonaiagents: before 1.6.58 (fixed in 1.6.58)
