Server path disclosure via unfiltered upload response

Published Aug 11, 2025 · Updated Aug 11, 2025

Information disclosure in Wukong CRM 11.0 allows remote authenticated users to read an absolute server path through the upload endpoint. The /adminFile/upload handler returns the full persisted file entity without filtering its absolute storage-path field from the API response. A valid low-privilege Admin-Token and a file upload are required; exposure is limited to server directory structure, enabling reconnaissance.
