ZFile through 5.0.5 Share Entry Filter Bypass via Download Endpoint

ZFile through 5.0.5 fails to validate requested file paths against a share link's allowed entries on the download endpoint. Attackers holding a share link can supply arbitrary file paths as query parameters to download any file under the shared base directory, bypassing the intended access restrictions.

ZFile v4.1.1 was discovered to contain an arbitrary file upload vulnerability via the component /file/upload/1.
