CVE-2026-47413

praisonai-platform: Any workspace member can add arbitrary user as owner via POST /workspaces/{id}/members

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 requireworkspacemember(workspace_id) (default min_role="member") and forwards the request body's user_id and role straight into MemberService.add(workspaceid, userid, 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.
