Summary

Type: Insecure Direct Object Reference. Five label endpoints — PATCH /workspaces/{workspace_id}/labels/{label_id}, DELETE .../labels/{label_id}, POST .../issues/{issue_id}/labels/{label_id}, DELETE .../issues/{issue_id}/labels/{label_id}, GET .../issues/{issue_id}/labels — gate access on require_workspace_member(workspace_id) only and pass URL-supplied label_id and issue_id straight through to LabelService without verifying either belongs to the workspace. File: src/praisonai-platform/praisonai_platform/services/label_service.py, lines 35-100; route handlers at src/praisonai-platform/praisonai_platform/api/routes/labels.py, lines 42-106. Root cause: identical pattern to the agent / issue / project / comment IDORs in this codebase: the route's workspace_id is used as a membership predicate but never threaded through to the service layer. LabelService.get(label_id) runs session.get(IssueLabel, label_id) with no workspace filter; update/delete inherit the gap; add_to_issue(issue_id, label_id) and remove_from_issue(issue_id, label_id) write/delete association rows without verifying either ID belongs to the membership-checked workspace; list_for_issue(issue_id) reads them.
