CVE-2026-47405

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.
