{"id":"CVE-2026-47395","aliases":["GHSA-5cxw-77wg-jrf3","PYSEC-2026-2903","PYSEC-2026-2942"],"url":"https://o3.security/vulnerability/CVE-2026-47395","summary":"PraisonAI CLI automatically resolves @url mentions in prompt text and can read loopback URLs into model context","details":"PraisonAI is a multi-agent teams system. Prior to version 4.6.40 of PraisonAI, corresponding to version 1.6.40 of praisonaiagents, PraisonAI's direct-prompt CLI automatically expands `@url:` mentions in raw prompt text before agent execution begins. If a prompt contains `@url:<http-or-https-url>`, the CLI calls `MentionsParser.process(...)`. The `@url:` handler then performs a direct `urllib.request.urlopen()` request to the attacker-controlled URL and returns the response body. That response body is prepended to the final model prompt context. There is no loopback/private-address restriction, no metadata-service restriction, and no approval gate before the fetch. As a result, attacker-influenced prompt text can cause the operator's machine to fetch localhost-only HTTP resources and inject the response into model context. PraisonAI version 4.6.40 and praisonaiagents version 1.6.40 contain a fix.","published":"2026-07-21T15:52:52.682Z","modified":"2026-08-12T03:51:13.076749948Z","cvss":{"score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N"},"epss":{"score":0.00129,"percentile":0.02985,"asOf":"2026-08-20"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"praisonaiagents","fixedVersion":"1.6.40"},{"ecosystem":"PyPI","name":"praisonai","fixedVersion":"4.6.40"}],"fix":{"url":"https://github.com/MervinPraison/PraisonAI/commit/b0d8f777528f3253a0cfb0a3ef65455da6ae32f6","label":"MervinPraison/PraisonAI@b0d8f77"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47395.json"},{"type":"ADVISORY","url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-5cxw-77wg-jrf3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47395"},{"type":"FIX","url":"https://github.com/MervinPraison/PraisonAI/commit/b0d8f777528f3253a0cfb0a3ef65455da6ae32f6"},{"type":"FIX","url":"https://github.com/MervinPraison/PraisonAI/pull/1684"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:13.076749948Z"}}
