PraisonAI (versiones 0.6.0 a 1.6.59 en praisonaiagents y 3.10.0 a 4.6.59 en PraisonAI) expone endpoints legados /sse y /messages/ sin validación de Host, Origin ni autenticación, permitiendo que sitios maliciosos ejecuten ataques de DNS rebinding contra instancias locales. Afecta especialmente a empresas que ejecutan sistemas multi-agente en infraestructura interna o en la nube privada. El CVSS de 8.3 refleja alto riesgo de compromiso de datos y control remoto.
PraisonAI is a multi-agent teams system. From praisonaiagents 0.6.0 until 1.6.59 and PraisonAI 3.10.0 until 4.6.59, ToolsMCPServer.run_sse() in src/praisonai-agents/praisonaiagents/mcp/mcp_server.py mounts SseServerTransport on the legacy /sse and /messages/ endpoints without default Host, Origin, or authentication enforcement. A malicious website can use DNS rebinding against a reachable local or internal SSE server, supply attacker-controlled Host and Origin headers, enumerate registered tools, and invoke them with the server user's privileges. The Streamable HTTP transport rejects the same hostile Origin, which isolates the flaw to the legacy SSE wrapper. An initial remediation was released in praisonaiagents 1.6.59 and PraisonAI 4.6.59.
