CVE-2026-57116

PraisonAI: AgentOS remains unauthenticated after GHSA-pm96 patched version and allows remote agent invocation

Published Oct 23, 2026 CVSS 3.1 · 9.8 Critical EPSS < 1% KEV · Not listed
Description
PraisonAI is a multi-agent teams system. From version 4.2.1 to before version 4.6.59, PraisonAI's AgentOS FastAPI deployment surface remains unauthenticated in current main and in releases after the published patched version for GHSA-pm96-6xpr-978x / CVE-2026-40151. The chat route directly calls agent.chat(request.message). No-auth and wrong-bearer requests both execute the deployed agent. This is broader than passive metadata disclosure. In any deployment where AgentOS wraps agents with tools, private context, memory, API integrations, or cost-bearing model calls, an unauthenticated reachable client can drive those agents. This issue has been patched in version 4.6.59.
