| Title | doccano v1.8.5 Broken Access Control |
|---|
| Description | The bulk-delete endpoint removes labels based only on the IDs provided in the request, without verifying that each label belongs to the project in the URL. This is a broken access control issue: a user with delete permission in one project can submit foreign label IDs from another project and delete those labels as well.This can cause cross-project data loss, label schema corruption, and inconsistent annotation state. In multi-user or multi-tenant deployments, it may disrupt other teams’ workflows and require manual recovery of deleted labels. |
