CVE-2026-47409

Full vulnerability record from the local CVENow database.

Description

PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have an authorization bypass enabling owner lockout. The `DELETE /workspaces/{workspace_id}/members/{user_id}` endpoint is gated only by `require_workspace_member(workspace_id)` (default `min_role="member"`). Any member can remove any other member, including the workspace owner, using a single DELETE. There is no caller-role check, no target-role check, no "cannot remove last owner" guard. PraisonAI Platform version 0.1.4 patches the issue.

Las versiones anteriores a la 0.1.4 tienen una omisión de autorización que permite el bloqueo del propietario. El endpoint “DELETE /workspaces/{workspace_id}/members/{user_id}” está protegido solo por “require_workspace_member(workspace_id)” (por defecto “min_role=“member””). Cualquier miembro puede eliminar a cualquier otro miembro, incluyendo al propietario del espacio de trabajo, usando una única solicitud DELETE. No hay verificación de rol del invocador, ni verificación de rol del objetivo, ni protección ’no se puede eliminar al último propietario’. La versión 0.1.4 de PraisonAI Platform corrige el problema."
