Until a fix is available, restrict access to the preview API endpoint, implement additional authentication or access controls, and monitor for unauthorized access attempts. Avoid sharing file IDs publicly to reduce exposure risk.
Description
Dromara free-fs versions 2.0.1 through 2.3.1 have a missing authentication vulnerability in the FileStreamController.preview function. This flaw allows unauthenticated attackers to download stored files by requesting the preview endpoint with a valid file ID. Attackers can obtain file IDs from share listings or preview links, enabling unauthorized access to any user's or workspace's files.
