File Browser Access Control and Bypass

Unauthorized file operations in File Browser before fix. PoC and patch available.

File Browser versions prior to 2.61.0 incorrectly set the filesystem root to a parent directory when generating public share links, enabling any user with a share link to access and download files from sibling directories beyond the intended shared folder. This authenticated network-based vulnerability affects Golang and Filebrowser and has public exploit code available. The issue is resolved in version 2.61.0 and later.
