Prior to praisonaiagents 1.6.58, the SSE server in src/praisonai-agents/praisonaiagents/server/server.py does not consult ServerConfig.auth_token before handling /publish, /events, or /info requests. A network client that can reach the server can broadcast arbitrary events to connected clients and obtain server configuration and client-count information. This issue is fixed in praisonaiagents 1.6.58.","published":"2026-09-14T14:25:42.764Z","modified":"2026-09-16T03:47:07.761528886Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"PyPI","name":"praisonaiagents","fixedVersion":"1.6.59"}],"fix":{"url":"https://github.com/MervinPraison/PraisonAI/commit/2f9677abb2ea68eab864ee8b6a828fd0141612e1","label":"MervinPraison/PraisonAI@2f9677a"},"references":[{"type":"WEB","url":"https://github.com/MervinPraison/PraisonAI/releases/tag/v4.6.58"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57128.json"},{"type":"ADVISORY","url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-35w5-pcw4-jx94"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57128"},{"type":"FIX","url":"https://github.com/MervinPraison/PraisonAI/commit/2f9677abb2ea68eab864ee8b6a828fd0141612e1"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-16T03:47:07.761528886Z"}}
