From version 4.2.1 to before version 4.6.59, 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 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. This issue has been patched in version 4.6.59.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-200","CWE-306","CWE-862"],"references":["https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-892r-p3jq-jp24"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:28.036610720+00:00"},"epss":{"cve":"CVE-2026-57116","score":0.00273,"percentile":0.19483,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-892r-p3jq-jp24","url":"https://osv.dev/vulnerability/GHSA-892r-p3jq-jp24","summary":"PraisonAI: AgentOS remains unauthenticated after incomplete fix version and allows remote agent invocation","modified":"2026-07-23T15:11:23.009337957Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":[">=4.2.1 <4.6.59"],"fixed":["4.6.59"]}]},{"id":"PYSEC-2026-3507","url":"https://osv.dev/vulnerability/PYSEC-2026-3507","summary":"PraisonAI: AgentOS remains unauthenticated after incomplete fix version and allows remote agent invocation","modified":"2026-07-23T15:00:20.690939654Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":[">=4.2.1 <4.6.59"],"fixed":["4.6.59"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
