PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have an authorization bypass enabling workspace metadata + settings tampering. The `PATCH /workspaces/{workspace_id}` endpoint is gated only by `require_workspace_member(workspace_id)` (default `min_role="member"`). Any member can rewrite the workspace's `name`, `description`, and the `settings` JSON blob. The settings field is a free-form JSON object — depending on which downstream code reads it, this becomes a configuration-injection primitive for any setting the platform exposes there. PraisonAI Platform version 0.1.4 patches the issue.

Affected: PyPI: praisonai-platform

## Summary

**Type:** Authorization bypass enabling workspace metadata + settings tampering. The `PATCH /workspaces/{workspace_id}` endpoint is gated only by `require_workspace_member(workspace_id)` (default `min_role="member"`). Any member can rewrite the workspace's `name`, `description`, and the `settings` JSON blob. The settings field is a free-form JSON object — depending on which downstream code reads it, this becomes a configuration-injection primitive for any setting the platform exposes there. **File:** `src/praisonai-platform/praisonai_platform/api/routes/workspaces.py`, lines 63-74; `services/workspace_service.py`'s `update()` method. **Root cause:** `Depends(require_workspace_member)` resolves to default `min_role="member"`. `WorkspaceService.update(workspace_id, name, description, settings)` writes the new fields to the workspace row without any caller-permission check. The role hierarchy (`MemberService.has_role`) is never consulted.
