What is CVE-2026-54096?

The vulnerability in File Browser allows an authenticated user to create a public share record for an arbitrary file path without confirming the target file's existence. This security oversight means that when a file is later created at that path, the public share becomes immediately valid, exposing the new file without proper authorization through a public download link. This issue has been addressed in version 2.63.7.

Affected Version(s)
