Unknown · Filebrowser · CVE-2026-72839
**Name of the Vulnerable Software and Affected Versions**
filebrowser versions prior to 2.63.17
**Description**
An issue exists when self-signup is enabled using the default `CreateUserDir` setting. Unauthenticated attackers can register accounts that inherit the server root scope, granting them full permissions to create, modify, delete, rename, share, and download all files on the server.
**Recommendations**
Update to a version newer than 2.63.16.
Disable the self-signup feature or modify the `CreateUserDir` setting to restrict user scope.
