{"id":"CVE-2026-57139","aliases":["GHSA-j4f3-55x4-r6q2"],"url":"https://o3.security/vulnerability/CVE-2026-57139","summary":"PraisonAI MCPServer exposes unauthenticated HTTP tools/call","details":"PraisonAI is a multi-agent teams system. From 1.5.0 until 1.7.2, MCPServer.startHttp() in src/praisonai-ts/src/mcp/server.ts binds without a host restriction and forwards every HTTP POST request to handleRequest() without authentication or authorization. Any network client that can reach the port can call tools/list, tools/call, resources/read, or prompts/get, causing registered handlers to run with server-side credentials and process privileges or disclose registered data. An initial remediation was released in version 1.7.2.","published":"2026-09-15T10:25:26.890Z","modified":"2026-09-16T03:47:08.972901153Z","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":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-2026-57139.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-j4f3-55x4-r6q2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57139"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-16T03:47:08.972901153Z"}}
