{"id":"CVE-2026-47405","aliases":["GHSA-h37g-4h4p-9x97","PYSEC-2026-2936"],"url":"https://o3.security/vulnerability/CVE-2026-47405","summary":"PraisonAI Platform missing role checks let any workspace member become owner and take over workspace membership","details":"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.","published":"2026-07-21T16:18:27.991Z","modified":"2026-08-12T03:51:49.072704089Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.0029,"percentile":0.21588,"asOf":"2026-08-20"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"praisonai-platform","fixedVersion":"0.1.4"}],"fix":{"url":"https://github.com/MervinPraison/PraisonAI/commit/24385d64876577620f749957bd4814f162f4ca47","label":"MervinPraison/PraisonAI@24385d6"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47405.json"},{"type":"ADVISORY","url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-h37g-4h4p-9x97"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47405"},{"type":"FIX","url":"https://github.com/MervinPraison/PraisonAI/commit/24385d64876577620f749957bd4814f162f4ca47"},{"type":"FIX","url":"https://github.com/MervinPraison/PraisonAI/pull/1686"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:49.072704089Z"}}
