{"id":"CVE-2026-47413","aliases":["GHSA-8g2p-pqm3-fcfh","PYSEC-2026-480"],"url":"https://o3.security/vulnerability/CVE-2026-47413","summary":"praisonai-platform: Any workspace member can add arbitrary user as owner via POST /workspaces/{id}/members","details":"PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have aprivilege escalation / cross-tenant member injection. The `POST /workspaces/{workspace_id}/members` endpoint is gated only by `require_workspace_member(workspace_id)` (default `min_role=\"member\"`) and forwards the request body's `user_id` and `role` straight into `MemberService.add(workspace_id, user_id, role)`, which has no caller-permission check. A user with the lowest workspace privilege can add any user (including a new attacker-controlled second account, or an existing account they want to grief) as owner of the workspace. PraisonAI Platform version 0.1.4 patches the issue.","published":"2026-07-21T17:07:21.546Z","modified":"2026-08-12T03:51:22.352916495Z","cvss":{"score":9.6,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N"},"epss":{"score":0.00209,"percentile":0.11368,"asOf":"2026-08-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"praisonai-platform","fixedVersion":"0.1.4"}],"fix":{"url":"https://github.com/MervinPraison/PraisonAI/commit/ef79b7a0561796ad9807f0f09538c25cc78d3619","label":"MervinPraison/PraisonAI@ef79b7a"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47413.json"},{"type":"ADVISORY","url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-8g2p-pqm3-fcfh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47413"},{"type":"FIX","url":"https://github.com/MervinPraison/PraisonAI/commit/ef79b7a0561796ad9807f0f09538c25cc78d3619"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:22.352916495Z"}}
