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.","published":"2026-07-21T15:39:28.459Z","modified":"2026-08-12T03:51:15.214085930Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.00403,"percentile":0.33625,"asOf":"2026-08-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"praisonai","fixedVersion":"4.6.40"}],"fix":{"url":"https://github.com/MervinPraison/PraisonAI/commit/ef79b7a0561796ad9807f0f09538c25cc78d3619","label":"MervinPraison/PraisonAI@ef79b7a"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47393.json"},{"type":"ADVISORY","url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-8444-4fhq-fxpq"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-6rmh-7xcm-cpxj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47393"},{"type":"FIX","url":"https://github.com/MervinPraison/PraisonAI/commit/ef79b7a0561796ad9807f0f09538c25cc78d3619"},{"type":"FIX","url":"https://github.com/MervinPraison/PraisonAI/pull/1685"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:15.214085930Z"}}
