{"id":"CVE-2026-57140","aliases":["GHSA-9752-mhqh-h34f"],"url":"https://o3.security/vulnerability/CVE-2026-57140","summary":"PraisonAI AgentOS exposes unauthenticated agent listing and invocation","details":"PraisonAI is a multi-agent teams system. From 1.6.0 until 1.7.2, AgentOS in src/praisonai-ts/src/os/agentos.ts uses the 0.0.0.0 default from src/praisonai-ts/src/os/config.ts and registers GET /api/agents and POST /api/chat without authentication middleware. A remote caller who can reach the service can obtain agent names, roles, and instruction prefixes and can invoke a selected agent, potentially reaching its tools, memory, external APIs, credentials, and workflow state. An initial remediation was released in version 1.7.2.","published":"2026-09-15T10:26:11.173Z","modified":"2026-09-16T03:47:07.763206669Z","cvss":{"score":9.4,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"praisonai","fixedVersion":"1.7.2"}],"fix":{"url":"https://github.com/MervinPraison/PraisonAI/commit/709a0387853709a5e2f2c34680fa64cada252c27","label":"MervinPraison/PraisonAI@709a038"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57140.json"},{"type":"FIX","url":"https://github.com/MervinPraison/PraisonAI/commit/709a0387853709a5e2f2c34680fa64cada252c27"},{"type":"WEB","url":"https://github.com/MervinPraison/PraisonAI/releases/tag/v4.6.60"},{"type":"ADVISORY","url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-9752-mhqh-h34f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57140"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-16T03:47:07.763206669Z"}}
