Prior to 4.5.128, the AgentOS deployment platform exposes a GET /api/agents endpoint that returns agent names, roles, and the first 100 characters of agent system instructions to any unauthenticated caller. The AgentOS FastAPI application has no authentication middleware, no API key validation, and defaults to CORS allow_origins=[\"*\"] with host=\"0.0.0.0\", making every deployment network-accessible and queryable from any origin by default. This vulnerability is fixed in 4.5.128.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-200"],"references":["https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-pm96-6xpr-978x"],"products":["praison:praisonai"],"source":"nvd","synced_at":"2026-10-26T21:38:48.864438205+00:00"},"epss":{"cve":"CVE-2026-40151","score":0.00758,"percentile":0.54941,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-pm96-6xpr-978x","url":"https://osv.dev/vulnerability/GHSA-pm96-6xpr-978x","summary":"PraisonAI: Unauthenticated Information Disclosure of Agent Instructions via /api/agents in AgentOS","modified":"2026-07-13T16:42:44.165681656Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":["<4.5.128"],"fixed":["4.5.128"]}]},{"id":"PYSEC-2026-2919","url":"https://osv.dev/vulnerability/PYSEC-2026-2919","summary":"PraisonAI: Unauthenticated Information Disclosure of Agent Instructions via /api/agents in AgentOS","modified":"2026-07-13T16:33:02.951899112Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":["<4.5.128"],"fixed":["4.5.128"]}]}],"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).
