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.\n**File:** `src/praisonai-platform/praisonai_platform/api/routes/workspaces.py`, lines 130-140; `services/member_service.py`, lines 71-78.\n**Root cause:** `MemberService.remove(workspace_id, user_id)` performs the deletion without any caller-permission check or owner-protection logic. The route accepts the URL-supplied `user_id` and dispatches it straight through. The role hierarchy (`MemberService.has_role`) is implemented but never invoked here. A member-tier attacker can issue `DELETE .../members/` and immediately lock the legitimate owner out of the workspace.\n\n## Affected Code\n\n**File 1:** `src/praisonai-platform/praisonai_platform/api/routes/workspaces.py`, lines 130-140.\n\n```python\n@router.delete(\"/{workspace_id}/members/{user_id}\", status_code=status.HTTP_204_N","public_affected_ranges":["<= 0.1.2"]}],"null_published_at":"2026-11-07T07:07:39.856Z","source_updated_at":"2026-05-29T22:57:07.000Z","source_disclosed_at":"2026-05-29T22:57:05.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-07T00:53:14.635Z"}],"next_cursor":null,"snapshot_revision":"42594"}
