Technical details
The ProjectBulkAssetEndpoint.post endpoint in apps/api/plane/app/views/asset/v2.py performs an insecure direct object reference (IDOR) by querying assets using only id__in and workspace__slug without constraining results to the project_id from the URL. An authenticated workspace guest can provide asset UUIDs from other projects and reassign their associated issue_id, comment_id, page_id, draft_issue_id, or project_id to attacker-controlled entities, causing Plane to generate presigned download URLs for the hijacked assets. The vulnerability requires workspace membership but not project permissions.
