Product: PraisonAI

Description

PraisonAI is a multi-agent teams system. CVE-2026-44338 (GHSA-6rmh-7xcm-cpxj) documents that PraisonAI ships a code-generator (`praisonai.deploy.api.generate_api_server_code`) that emits a Flask API server with authentication disabled by default. Users who follow the documented quickstart (`praisonai deploy --type api`) get a server that binds to `0.0.0.0` per the recommended sample YAML, exposes `/chat` and `/agents` endpoints, runs `praisonai.run()` on user-supplied JSON input — LLM orchestration with the API key materials present in the process environment, and does not require any authentication. Versions prior to 4.6.40 still ship the generator with `auth_enabled` defaulting to `False`. The fix shape is opt-in via `APIConfig(auth_enabled=True, auth_token=...)`. Version 4.6.40 fixes the issue.

Technical Analysis

PraisonAI's code-generator (`praisonai.deploy.api.generate_api_server_code`) produces a Flask API server with authentication disabled by default. Users following the documented quickstart receive a server binding to all interfaces (0.0.0.0) exposing `/chat` and `/agents` endpoints without requiring authentication. This allows unauthenticated access to LLM orchestration functions that use API key materials present in the environment. Versions prior to 4.6.40 have this insecure default; version 4.6.40 introduces an opt-in authentication configuration (`APIConfig(auth_enabled=True, auth_token=...)`) to remediate the issue.

Potential Impact

The vulnerability allows unauthenticated remote attackers to access critical API endpoints, potentially leading to full compromise of the LLM orchestration environment, exposure of API keys, and unauthorized use or manipulation of the system. The CVSS score of 9.8 reflects the critical confidentiality, integrity, and availability impacts.

Mitigation Recommendations

Upgrade PraisonAI to version 4.6.40 or later, where authentication is enabled by default via configuration. Users should configure `APIConfig(auth_enabled=True, auth_token=...)` to enforce authentication on the generated API server. Since this is a code-generator default setting, users must ensure they do not deploy servers with authentication disabled. Patch status is confirmed fixed in version 4.6.40.
