PYSEC-2026-3507 — PraisonAI: AgentOS remains unauthenticated after incomplete fix version and allows remote agent invocation

Affected: PyPI: praisonai

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

## Summary

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 public AgentOS advisory is published as an instruction-disclosure issue with affected versions `< 4.5.128` and patched version `4.5.128`. However, `v4.5.128`, latest release `v4.6.57`, and current main still register `GET /api/agents` and `POST /api/chat` without authentication. 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.
