{"id":"CVE-2026-47405","state":"PUBLISHED","title":"PraisonAI Platform missing role checks let any workspace member become owner and take over workspace membership","description":"PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have a broken workspace authorization check that allows any authenticated low-privilege workspace member to escalate their own role to `owner`. The issue is caused by privileged workspace-management routes using the shared dependency `require_workspace_member(...)` without requiring `admin` or `owner`. The dependency defaults to `min_role=\"member\"`, so routes that should be administrative are accessible to ordinary workspace members. As a result, a normal workspace member can promote their own account from `member` to `owner`; add arbitrary users as `owner` or `admin`; change other members' roles; remove legitimate owners or members; take over workspace membership completely; and/or perform destructive workspace operations after escalation. This is a broken access control / vertical privilege escalation vulnerability. PraisonAI Platform version 0.1.4 patches the issue.","publishedAt":"2026-07-21T16:18:27.991Z","updatedAt":"2026-07-21T17:59:03.862Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["MervinPraison praisonai-platform"],"affected":[{"vendor":"MervinPraison","product":"praisonai-platform","versions":[{"version":"< 0.1.4","status":"affected"}]}],"references":["https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-h37g-4h4p-9x97","https://github.com/MervinPraison/PraisonAI/pull/1686","https://github.com/MervinPraison/PraisonAI/commit/24385d64876577620f749957bd4814f162f4ca47"],"weaknesses":["CWE-284","CWE-862"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/47xxx/CVE-2026-47405.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-47405","state":"PUBLISHED","datePublished":"2026-07-21T16:18:27.991Z","dateUpdated":"2026-07-21T17:59:03.862Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-19T19:37:43.525Z"},"containers":{"cna":{"title":"PraisonAI Platform missing role checks let any workspace member become owner and take over workspace membership","descriptions":[{"lang":"en","value":"PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system.
