CVE-2026-57140

PraisonAI AgentOS exposes unauthenticated agent listing and invocation

Published: Sep 15, 2026Updated: Sep 15, 2026 Sources: CVE List NVDCWE-306

9.4CRITICAL

Description

PraisonAI is a multi-agent teams system. From 1.6.0 until 1.7.2, AgentOS in src/praisonai-ts/src/os/agentos.ts uses the 0.0.0.0 default from src/praisonai-ts/src/os/config.ts and registers GET /api/agents and POST /api/chat without authentication middleware. A remote caller who can reach the service can obtain agent names, roles, and instruction prefixes and can invoke a selected agent, potentially reaching its tools, memory, external APIs, credentials, and workflow state. An initial remediation was released in version 1.7.2.
