{"id":"CVE-2026-47395","state":"PUBLISHED","title":"PraisonAI CLI automatically resolves @url mentions in prompt text and can read loopback URLs into model context","description":"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.","publishedAt":"2026-07-21T15:52:52.682Z","updatedAt":"2026-07-21T17:15:13.196Z","severity":{"score":5.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["MervinPraison PraisonAI","MervinPraison praisonaiagents"],"affected":[{"vendor":"MervinPraison","product":"PraisonAI","versions":[{"version":"< 4.6.40","status":"affected"}]},{"vendor":"MervinPraison","product":"praisonaiagents","versions":[{"version":"< 1.6.40","status":"affected"}]}],"references":["https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-5cxw-77wg-jrf3","https://github.com/MervinPraison/PraisonAI/pull/1684","https://github.com/MervinPraison/PraisonAI/commit/b0d8f777528f3253a0cfb0a3ef65455da6ae32f6"],"weaknesses":["CWE-200"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/47xxx/CVE-2026-47395.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-47395","state":"PUBLISHED","datePublished":"2026-07-21T15:52:52.682Z","dateUpdated":"2026-07-21T17:15:13.196Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-19T19:22:45.729Z"},"containers":{"cna":{"title":"PraisonAI CLI automatically resolves @url mentions in prompt text and can read loopback URLs into model context","descriptions":[{"lang":"en","value":"PraisonAI is a multi-agent teams system.
