EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 67% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
