FileBrowser before 2.63.19 does not account for case-insensitive filesystems when checking home directory ownership during self-registration. When Signup and CreateUserDir are enabled and FileBrowser's root is on a case-insensitive filesystem confirmed on Windows/NTFS, two self-registered usernam...

CVE-2026-72836

Affected: FileBrowser before 2.63.19. Root on a case-insensitive filesystem (e.g., Windows/NTFS) allows two self-registered usernames that differ only by case to resolve to the same home directory, because the scope-ownership check uses an exact case-sensitive comparison. This enables an attacker...
