CVE-2026-57128 PUBLISHED

PraisonAI: Unauthenticated Event Injection via SSE `/publish` Endpoint

Assigner: GitHub_M
Reserved: 24.06.2026 Published: 14.09.2026 Updated: 14.09.2026

PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.58, the SSE server in src/praisonai-agents/praisonaiagents/server/server.py does not consult ServerConfig.auth_token before handling /publish, /events, or /info requests. A network client that can reach the server can broadcast arbitrary events to connected clients and obtain server configuration and client-count information. This issue is fixed in praisonaiagents 1.6.58.
