Summary

A vulnerability in PraisonAI before version 4.6.78 allows authentication bypass in the Call API agent invocation endpoints (agent_invoke.py) when PRAISONAI_CALL_AUTH=disabled is configured. The safeguard restricting access to localhost relies on the HTTP Host header, which can be spoofed by an attacker.

Risk Assessment

A remote, unauthenticated attacker can list registered agents (GET /api/v1/agents) and invoke any agent (POST /api/v1/agents/{agent_id}/invoke) without authentication, leading to unauthorized access and potential system compromise.

Recommendation

Upgrade PraisonAI to version 4.6.78 or later immediately. If upgrading is not possible, disable the PRAISONAI_CALL_AUTH=disabled option and configure authentication for all API endpoints.

Original NVD description (English source)

PraisonAI before 4.6.78 contains an authentication bypass in the Call API agent invocation endpoints (src/praisonai/praisonai/api/agent_invoke.py) when PRAISONAI_CALL_AUTH=disabled is configured. The safeguard intended to restrict the disabled-auth opt-out to localhost binding derives the bind host from request.url.hostname, which is taken from the client-controlled HTTP Host header. A remote, unauthenticated attacker who can reach the service over the network can send a spoofed 'Host: 127.0.0.1' header to bypass the localhost-only restriction and list (GET /api/v1/agents) and invoke (POST /api/v1/agents/{agent_id}/invoke) registered agents without authentication.
